Silicon carbide (SiC) is a lightweight ceramic material with high strength properties comparable to diamond. It has high thermal conductivity, low thermal expansion, thermal shock resistance, oxidation resistance, and corrosion resistance. Silicon carbide is an excellent ceramic raw material for applications requiring good erosion and abrasive resistance. Consequently, it is useful in a variety of industrial applications including spray nozzles, shot blast nozzles, kiln furniture, and cyclone components.
China Special Ceramic Parts, Inc.(CSCPI) produces sintered silicon carbide refractory plates, reaction bonded SiC ceramic plates and recrystallized SiC plates. Our recrystallized SiC products have a high purity, while our reaction bonded and sintered silicon carbide plates have a high mechanical strength.
