Small Chlorine Furnace | Capable of Removing Metal Impurities Difficult to Eliminate with Wet and Magnetic Separation

Reduce wastewater from wet processing and drying processes, and remove metal impurities through selective chlorination.

In powder raw materials and functional materials, metal impurities such as Fe, Cu, and Ni can affect product characteristics and yield. Particularly in battery materials, ceramics, semiconductor materials, and high-purity powders, there is an increasing demand for managing metal impurities at levels ranging from ppm to ppb. Traditionally, methods such as wet processing for dissolution removal and magnetic separation for recovering magnetic particles have been common. However, wet processing poses challenges related to wastewater treatment, drying processes, and recontamination, while magnetic separation can struggle to remove non-magnetic metal compounds and fine adherents. To address these issues, we propose a "small chlorine furnace" that uses halogen gases such as Cl2 and HCl to convert metal impurities into volatile chlorides for separation. [For such challenges] ■ We want to reduce wastewater and drying processes in wet processing. ■ We want to reduce Fe/Cu/Ni impurities at ppm to ppb levels. ■ We want to remove metal impurities that cannot be captured by magnetic separation. ■ We want to process impurities within powders, porous bodies, and ceramics. ■ We want to confirm Cl2/HCl treatment conditions with small sample sizes. *For more details, please download the materials or contact us.

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

Selection of furnace for vacuum atmosphere sintering | Supports degassing, oxidation suppression, and high purity processing.

Select the appropriate electric furnace according to the vacuum level and processing purpose.

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

Differences between sintering, heat treatment, degreasing, and reduction | Selecting electric furnaces by purpose

Organize electric furnaces suitable for sintering, heat treatment, degreasing, and reduction.

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

Selection of Furnace for H₂ Reduction Atmosphere Heat Treatment | Measures for Safety and H₂ Concentration Management

Organize furnace specifications based on H₂ concentration, dilution gas, and safety measures.

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

Selection of furnace for Cl₂・HCl special atmosphere sintering | Corresponding to chlorination reaction and corrosion evaluation

Organize the firing conditions and safety specifications using corrosive gases.

Are you considering sintering, chlorination reactions, and corrosion evaluation in a special atmosphere such as Cl₂ and HCl? In sintering using corrosive and reactive gases like Cl₂ and HCl, it is necessary to consider specifications not only for temperature and gas concentration but also for materials inside the furnace, jig materials, sealing materials, piping, valves, exhaust piping, pollution control devices, and safety interlocks. In particular, for chlorination reactions and volatile separation, the volatility of the generated chlorides, condensation location, recovery methods, insulation of exhaust piping, and pollution control capabilities are important. Additionally, since corrosive gases are handled, leak prevention measures, gas detection, exhaust routes, and safety shutdown conditions significantly impact equipment specifications. This document organizes the treatment objectives, gas conditions, furnace type selection, and key points for confirming jigs, piping, exhaust, pollution control, and safety measures in Cl₂ and HCl special atmosphere sintering. - For sintering and reaction evaluation in Cl₂ and HCl atmospheres - For consideration of chlorination reactions, volatile separation, and impurity removal - For removal of deposits from jigs and components, and evaluation of corrosion and durability - For insulation of exhaust, condensation measures, and specification review of pollution control devices - For sintering tests and condition exploration before equipment installation
