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

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
