Silicon Carbide Ceramics
Silicon carbide is an inorganic substance with a chemical formula of SiC. It is made by high temperature smelting of raw materials such as quartz sand, petroleum coke (or coal coke), and wood chips through a resistance furnace. Silicon carbide also exists in nature, a rare mineral, moissanite. Among the non-oxide high-tech refractory materials such as C, N, and B, silicon carbide is the most widely used and most economical one. Sintered silicon carbide (SSiC) is processed by pressureless sintered from high purity ultra-fine silicon carbide powder in vacuum furnace at the temperature of 2100°C – 2200°. with premium mechanical performance, strongly resistance to granular abrasion, high temperature, particularly combined with rubber sheet as super abrasion resistant wear plate, or being high-efficiency machine components like drive pumps, sleeves, seal rings, nozzles, bushes etc.
