Product introduction
Fused-cast synthetic mica is a microcrystalline ceramic material made by direct melting and casting of synthetic fluorphlogopite fragments. It not only maintains the understanding of mica, so that it can be processed by turning, milling, planing, grinding, drilling, cutting and other mechanical processing, and has good electrical insulation, high temperature resistance and thermal shock resistance of fluorophlogopite, and is widely used. Used in electron beam welding machine lining, intermediate frequency induction furnace lining, ion nitriding furnace cathode insulating parts, copier heating parts skeleton. In addition, fused-cast synthetic mica also has good chemical stability, and can be used for a long time in hydrogen, ammonia, nitrogen, chlorine and other atmospheres without corrosion and corrosion of molten aluminum alloy and other liquid metals. It is used for strong corrosion-resistant parts in chemical plants. The pump grooves, valves, joints, etc. of the combined gold can also be used to make metallurgical crucibles, gas chromatography detection elements, etc.
