Silicon carbide (SiC) is a compound of silicon and carbon with a chemical formula of SiC. The simplest manufacturing process for producing silicon carbide is to combine silica sand and carbon in an Acheson graphite electric resistance furnace at a high temperature, between 1600°C (2910°F) and 2500°C (4530°F).
Silicon carbide bricks are a kind of refractory brick used high purity silicon carbide(SIC) and industrial silicon powder as the primary materials. Silicon carbide bricks have the advantages of wear resistance, good erosion resistance, high strength, excellent thermal conductivity and thermal shock resistance, good oxidation resistance, low porosity and better adhesion resistance,etc.
Silicon carbide is not attacked by any acids or alkalis or molten salts up to 800°C. In air, SiC forms a protective silicon oxide coating at 1200°C and is able to be used up to 1600°C. The high thermal conductivity coupled with low thermal expansion and high strength give this material exceptional thermal shock resistant qualities.
