"Although the temperature is achieved, the targeted reaction site cannot be created." In high-temperature processing of carbon materials, ceramics, and high-melting-point materials, simply raising the temperature is not sufficient. Slight differences in furnace oxygen, heating rate, thermal history, and furnace atmosphere can lead to oxidation/re-oxidation, characteristic fluctuations, and reaction inconsistencies. This document explains the capabilities of the "small carbon furnace," which balances an ultra-low oxygen atmosphere with high-temperature processing in the range of 2,000 to 3,000°C, from a practical perspective. [For challenges like these] ■ Heating can be done, but the sample state and characteristics are unstable. ■ Large furnaces take time to start up, making it difficult to establish conditions. ■ We want to suppress oxidation/re-oxidation during high-temperature processing. ■ We want to align oxygen management and thermal history to reproduce crystallinity, conductivity, and microstructure. The small carbon furnace facilitates short trial runs, condition changes, oxygen management, and thermal history management, making it suitable for condition exploration in research and development or prototype stages. *For more details, please download the document or contact us.

While the demand for dry and reduction-type heat treatment is increasing, there are challenges in research settings such as "insufficient temperature," "incompatible charge sizes," and "difficulty in maintaining low-oxygen atmospheres." In particular, for the graphitization of carbon materials, carbonization and nitridation of ceramics, and dry processing of battery materials and catalyst supports, conventional electric furnaces may lack the necessary temperature, atmosphere, and processing space. Our small carbon furnace aims to achieve short heating times, high-temperature uniformity, and low-oxygen atmospheres through the use of graphite heating elements, high insulation structures, vacuum replacement, and inert gas atmosphere control. **Main Challenges in Research Settings** - Limitations on maximum achievable temperature prevent the reproduction of high-temperature processing conditions. - The small amount of charge sample and effective heating area make scaling difficult. - Maintaining a low-oxygen atmosphere is challenging, leading to oxidation and re-oxidation. - There is a desire to investigate dry reduction, graphitization, carbonization, and nitridation conditions using a small furnace. *For more details, please download the materials or contact us.*

The small carbon furnace is characterized by its ability to achieve both an extremely low oxygen atmosphere and ultra-high temperature processing at around 3000°C. This document explains why it is possible to maintain a low oxygen environment and why high-temperature processing at around 3000°C is achievable, from the perspectives of furnace materials, vacuum replacement, inert gas purging, and thermal design. By constructing the interior of the furnace with graphite components, it becomes easier to suppress the influence of oxidative components such as residual O2, CO2, and H2O in high-temperature regions. Additionally, by combining vacuum pumping with inert gas replacement using Ar/N2, the air remaining inside the powder and the furnace is expelled, creating an atmosphere suitable for processing materials that are sensitive to oxidation.

In the aerospace field, the quality stability of heat-resistant components and composite materials used in high-temperature environments is crucial. For the firing of turbine parts, rocket-related components, C/C composites, and ceramic materials, not only temperature conditions but also vacuum and inert atmosphere control to suppress oxidation are required. Our carbon furnace supports high-temperature heating up to 3000°C and enables high-temperature firing in a low-oxygen atmosphere by replacing the environment with Ar, N2, etc., after vacuuming. We offer custom designs based on the material, size, temperature, and atmosphere of the items being processed, including firing, carbonization, graphitization, sintering, and heat treatment conditions for heat-resistant components. ■ I want to consider firing conditions for heat-resistant components for aerospace applications. ■ I want to perform high-temperature processing above 2000°C. ■ I want to process C/C composites and ceramic materials. ■ I want to fire in a vacuum or inert atmosphere that suppresses oxidation. ■ I would like to consult from research and development to prototype and pre-mass production evaluation.

In the development of new materials and research applications, a high-temperature furnace that can extensively examine the thermal treatment conditions of materials is essential. In particular, for high-temperature sintering above 2000°C, carbonization and graphitization, ceramic sintering, and thermal treatment of powder materials, atmosphere control such as vacuum, inert gas, and low-oxygen environments becomes crucial. Our carbon furnace supports high-temperature heating up to 3000°C and enables high-temperature processing with reduced oxidation by replacing the atmosphere with inert gases such as Ar and N2 after vacuum pumping. We offer custom designs based on the size, temperature, atmosphere, and processing volume of the materials, ranging from small furnaces for research and development to equipment for prototype evaluation and pre-mass production studies. We can accommodate research and development themes such as the following: ■ High-temperature sintering and thermal treatment of new materials ■ Examination of high-temperature processes above 2000°C ■ Carbonization and graphitization of carbon materials ■ Sintering of non-oxide ceramics such as SiC, AlN, and BN ■ Sintering of battery materials, negative electrode materials, and conductive materials ■ Evaluation of powder molded bodies, pellets, and sintered bodies ■ Sintering under atmosphere control with vacuum, Ar, N2, etc. ■ Scale-up studies from laboratory scale to pre-mass production evaluation

In the densification of ceramic materials, it is necessary to examine the optimal heat treatment conditions for each material, including debinding, pre-sintering, sintering, pressure sintering, and atmosphere control. In particular, when high-temperature processing is desired while suppressing oxidation, or when the temperature, atmosphere, and furnace dimensions of a conventional electric furnace do not meet requirements, the use of a carbon furnace is effective. Our carbon furnace supports high-temperature heating up to 3000°C and enables firing in a low-oxygen atmosphere by replacing the environment with inert gases such as Ar or N2 after vacuum pumping. Custom designs tailored to specific purposes are possible, ranging from research and development to mass production equipment, for applications such as densification of ceramics, promotion of sintering, phase formation, and high-temperature processing after debinding.

When introducing an electric furnace, it can be difficult to determine the equipment specifications if conditions such as temperature, atmosphere gas, processing time, pressure, sample amount, exhaust gas, and safety measures are still uncertain. Small-scale tests under special conditions that are difficult to accommodate in general electric furnaces, such as corrosive gases like Cl2/HCl, reducing atmospheres like H2, oxidizing atmospheres like O2/Air, NH3 atmospheres, humidified atmospheres, and vacuum/N2/Ar atmospheres, are possible. 【Examples of tests that can be conducted】 ■ Dry removal of metal impurities and selective chlorination using Cl2/HCl ■ Reduction firing and deoxidation treatment using H2 ■ Oxidation firing and surface oxidation treatment using O2/Air ■ Nitriding treatment and reactivity confirmation using NH3 You can consult us even at the stage where conditions are uncertain, such as "Can firing be done under these conditions?", "Can this gas atmosphere be accommodated?", and "Can we consider the generated gases and exhaust treatment?" Even if the material name, processing temperature, atmosphere gas, and processing purpose are not determined, we will support the examination of furnace types, test conditions, and safety configurations at our company. *For examples of tests that can be conducted and the approach, please download the materials or contact us.

Are you having trouble selecting a furnace or electric furnace? If you choose an electric furnace based solely on maximum temperature, mismatches may occur in terms of operating atmosphere, vacuum level, gas flow, sample size, safety measures, and exhaust gas treatment. This document compares multi-atmosphere furnaces, tube furnaces, metal furnaces, carbon furnaces, and small chlorine furnaces in terms of temperature range, compatible atmospheres, preferred applications, and points to note. ■ Quickly understand the differences between furnace types ■ Useful for specification discussions before equipment installation ■ Effective for preliminary organization of firing tests and condition exploration ■ Also addresses confirmation of firing feasibility in special atmospheres

In firing tests, the type of furnace, fixtures, containers, and recovery methods vary depending on "what is being fired." The points to be checked and the items to be evaluated differ for powders, substrates and plates, fixtures and parts, and molded bodies and pellets. For example, with powders, it is important to check for dispersibility, moisture absorption, and recovery methods; for substrates, warping, distortion, and in-plane temperature differences; for fixtures and parts, gas flow and dead spots; and for molded bodies, cracks, shrinkage, and contact marks. This document organizes the items to be checked before firing tests by sample type, considerations for selecting fixtures and containers, and perspectives for selecting furnace types in a list format. ■ For consideration of firing tests before equipment introduction ■ For organizing conditions of powders, substrates, fixtures, and parts ■ For initial considerations in selecting furnace types, fixtures, and containers

Before introducing an electric furnace, are there any omissions in the specification review? It is necessary to organize the specifications not only for the maximum temperature but also for the processing purpose, atmosphere gas, pressure conditions, sample conditions, containers and fixtures, exhaust gas treatment, safety measures, and installation conditions. This document organizes 10 items to check before the introduction of electric furnaces and atmosphere furnaces in a checklist format. ■ For organizing specifications before equipment introduction ■ For confirming conditions before firing tests ■ For initial considerations of special atmospheres, vacuum, reduction, and nitriding treatments ■ Can be used as internal confirmation materials before requesting estimates Please feel free to consult us even if you are at the stage of "not knowing which conditions to communicate to the manufacturer."

Before deciding on the specifications for electric furnaces and atmosphere furnaces, have you organized the conditions that should be confirmed through firing tests? In firing tests conducted before equipment installation, it is important to verify whether "the desired reaction occurs," "it can be processed safely," and "it can be scaled up to mass production conditions" using small sample sizes. This document organizes the planning items for confirming reactivity, safety, and reproducibility by varying temperature, atmosphere, processing time, flow rate, and pressure, focusing on processes such as firing, debinding, reduction, oxidation, nitriding, degassing, and impurity removal. ■ For exploring conditions before equipment installation ■ To prevent omissions in firing test planning ■ For consideration of furnace volume, gas systems, exhaust gas treatment, and jig specifications ■ For making scale-up decisions to mass production furnaces

In vacuum atmosphere sintering, the required pressure and furnace configuration vary depending on the purpose. For degassing and drying, a pressure range of several Pa to several hundred Pa is sufficient, while for oxidation suppression, vacuum pumping and N₂/Ar replacement are necessary, and for high-purity processing, high vacuum levels of 10⁻³ to 10⁻⁴ Pa may be required. Therefore, it is important to consider not only the simple condition of wanting to sinter in a vacuum but also the processing purpose, temperature range, residual O₂, amount of generated gas, materials inside the furnace, heater materials, exhaust system, and safety measures. This document organizes the necessary pressure guidelines, furnace type selection, and confirmation points that affect equipment specifications based on the purposes of vacuum atmosphere sintering. - For considerations of degassing, drying, and oxidation suppression - For considerations of sintering in high vacuum and high-purity atmospheres - For differentiating between metal furnaces, multi-furnaces, carbon furnaces, and tube furnaces - For organizing specifications and considering sintering tests before equipment installation

Are you able to organize the differences between firing, heat treatment, degreasing, and reduction? Even with the same "heat treatment," the necessary temperature range, atmosphere, exhaust gas measures, safety measures, temperature distribution, and sample collection methods change depending on the purpose. For example, in firing, reaction completion and temperature distribution are important; in degreasing, generated gases, tar, and rapid reactions are critical; in reduction, H₂ concentration, substitution management, and explosion limits are key; and in heat treatment, uniformity, cooling conditions, and high-purity atmosphere are essential. This document organizes the representative conditions, main atmospheres, key points, suitable types of furnaces, and pre-check items for firing, heat treatment, degreasing, and reduction in a list format. ■ For selecting electric furnaces and atmosphere furnaces that match the treatment purpose ■ For organizing conditions before equipment installation ■ For preliminary consideration of firing tests and condition exploration ■ Can be used as internal confirmation materials before requesting estimates

Are you considering firing tests of small sample sizes in the research and development or prototype stage? In the early stages of material development, there are often cases where large sample sizes cannot be prepared. Even in such cases, by using small samples and varying factors such as temperature, holding time, heating rate, atmosphere, and pressure, you can identify issues related to firing feasibility, reactivity, recoverability, and equipment implementation. At Thermonik ENG, we select the appropriate type of furnace from options such as multi-atmosphere furnaces, tube furnaces, metal furnaces, carbon furnaces, and chlorine furnaces based on the sample size, shape, and processing purpose, and connect the test results to the consideration of equipment specifications. - For exploring conditions in the research and development or prototype stage - For firing evaluation of small powders, molded bodies, substrates, jigs, and components - For initial considerations of temperature, atmosphere, and processing time - For confirming firing feasibility before equipment installation

Are you having trouble determining firing temperature, holding time, and atmospheric conditions in material development?

Additionally, there may be instances where you want to compare multiple atmospheres such as N₂, Ar, H₂, NH₃, vacuum, humidification, Cl₂, HCl, or check the furnace configuration suitable for powders, molded bodies, substrates, jigs, and components. At Thermonik ENG, we assist from the stage where conditions are not yet finalized by organizing objectives and sample conditions, and we support prototype evaluations by varying temperature, time, and atmosphere in a small furnace. The results obtained are reflected in the specifications of the equipment and furnace design, including internal dimensions, heaters, insulation, gas systems, and exhaust safety design. - For exploring firing conditions in the material development stage - For prototype evaluation and reactivity confirmation in a small furnace - For cross-examination of multiple atmospheres and furnace types - For specification and furnace design considerations before equipment installation

Are you selecting electric furnaces for research and development solely based on maximum temperature? In research and development, particularly in material development, there are cases where you want to compare multiple conditions of temperature, time, and atmosphere while the firing conditions are not yet established. Additionally, challenges may arise such as having a small sample size, wanting to use atmospheres like N₂, Ar, H₂, NH₃, O₂, vacuum, or humidified air, and needing to check safety aspects like powder dispersion, gas generation, corrosion, and explosion limits. This document organizes the specifications that should be confirmed when considering electric furnaces for research and development, as well as guidelines for selecting furnace types based on purpose. ■ For selecting electric furnaces in the research and development and material development stages ■ For initial considerations in prototyping, condition exploration, and small-scale firing ■ For considering firing tests in multiple atmospheres ■ For organizing specifications before requesting estimates ■ Can be used as internal discussion material before equipment introduction Even at a stage where conditions are not yet determined, we will propose ways to proceed with firing tests and equipment specifications based on sample shape, temperature range, and atmospheric conditions.

Are you considering sintering and heat treatment with N₂・Ar atmosphere to suppress oxidation? Simply flowing inert gas is not sufficient to suppress oxidation. It is necessary to determine conditions that include the introduction of oxygen and moisture into the furnace, replacement procedures, gas flow rates, dew point, residual O₂, sample shape, jig material, and re-oxidation during cooling. Additionally, while N₂ is relatively low-cost and easy to use for general oxidation suppression, there is a possibility of nitriding or reactions depending on the material. Ar/He has low reactivity and is suitable for high-purity processing and high-temperature treatments, but it is important to consider gas costs, replacement amounts, and leak management. This document organizes the differentiation of gas types in N₂・Ar/He atmosphere sintering, furnace selection, and confirmation items such as dew point, residual O₂, and replacement procedures. ■ For oxidation suppression in N₂・Ar atmosphere ■ For sintering and heat treatment in inert atmosphere ■ For confirming the differentiation between N₂ and Ar/He ■ For organizing conditions of dew point, residual O₂, and replacement procedures ■ For sintering tests and furnace type selection before equipment installation

Are you considering thermal treatment and firing evaluation in an H₂ reduction atmosphere? In processing under an H₂ reduction atmosphere, it is important to first clarify "what you want to reduce." Depending on the objective—such as the reduction of oxides, removal of surface oxide films, reduction of metallic impurities and residues, or treatment of powders, substrates, jigs, and components—the required temperature, H₂ concentration, holding time, and evaluation criteria will vary. Additionally, when processing with 100% H₂, high reduction power can be expected; however, it is crucial to consider specifications for replacement procedures, leak management, exhaust dilution, decontamination, and safety interlocks. When processing with diluted H₂ below the explosion limit, it is easier to lean towards safety, but there may be a risk of insufficient reducing power, necessitating verification of temperature, time, flow rate, and dilution ratio. This document organizes the reduction objectives, H₂ concentration, dilution gas, furnace configuration, safety measures, and points for reflecting on equipment specifications in H₂ reduction atmosphere thermal treatment. - For thermal treatment and firing evaluation in an H₂ reduction atmosphere - For comparative examination of 100% H₂ and diluted H₂ conditions - For oxide reduction, deoxygenation, and removal of surface oxide films - For organizing specifications of H₂ gas replacement, exhaust dilution, and safety interlocks - For firing tests and furnace type selection before equipment installation
