Small chlorine furnace <Removal of metal impurities from ceramics powder by dry chlorination>

Selectively volatilize Fe/Ni/Cr mixed in ceramic powder through chloride volatilization!

The "small chlorine furnace" is a product that maintains phase and particle size through negative pressure operation and oxygen partial pressure control, minimizing waste liquid without the need for cleaning. By using Cl2/HCl for selective chlorination, it removes metal impurities mixed in during the production of ceramic powder (SiO2/Al2O3/Si3N4) in a dry process. Additionally, by volatilizing chlorine, it reduces impurities in a short time while maintaining the composition, crystal phase, and particle size distribution of the mother phase. This allows for the elimination of the washing process, thereby reducing re-drying and waste liquid treatment costs. 【Features】 ■ Selective chlorination × temperature staging: Prioritizes the volatilization of metal chlorides while maintaining the base material phase. ■ Dry process: Minimizes the burden of waste liquid and re-drying without the need for washing. ■ Physical property retention design: Maintains crystal phase, particle size, and specific surface area through control of oxygen partial pressure and residence time. *For more detailed information, please download the materials or feel free to contact us.
