What are the application areas of silicon carbide?
Author:
In roller kilns, tunnel kilns and shuttle kilns in high-grade daily-use ceramics, sanitary porcelain, high-voltage electric porcelain, glass and other industries, silicon carbide ceramics are usually selected as high-temperature kiln furniture materials. For example, silicon carbide beams are suitable for load-bearing structural frames in industrial kilns. It has excellent high-temperature mechanical properties, good high-temperature creep resistance and no bending deformation after long-term use. Silicon carbide roller bar has good thermal conductivity for high temperature firing belt, save energy consumption at the same time do not increase the weight of the kiln car; silicon carbide cold air pipe used in the kiln cooling zone has good cold and heat resistance, and its service life is 5 to 10 times that of refractory materials such as stainless steel pipes or alumina.

Silicon carbide hardness after diamond and hexagonal boron nitride, is a commonly used abrasive. Because of its super hard performance, can be prepared into a variety of grinding wheels, abrasive cloth, sandpaper and all kinds of abrasive, widely used in machining industry. Silicon carbide is mainly divided into two kinds of black silicon carbide and green silicon carbide. Black silicon carbide relative to green silicon carbide hardness is low, used to grind low hardness materials, such as cast iron and non-metallic materials; green silicon carbide suitable for grinding hard alloy, optical glass, titanium alloy and the like, there is a cubic silicon carbide dedicated to the ultra-fine grinding of miniature bearings.
