GTEK Silicon Carbide




Reaction bonded silicon carbide is made by infiltrating compact made of mixtures of SiC and carbon with liquid silicon. The silicon reacts with the carbon forming more SiC which bonds the initial SiC particles. Reaction bonded silicon carbide has excellent wear, impact and chemical resistance. It can be formed into a variety of shapes, including cone and sleeve shapes, as well as more complex engineered pieces designed for equipment involved in mineral processing industry.
