One of the lightest, hardest, and strongest technical ceramic materials, SiC orcarborundum, has exceptional thermal conductivity, resistance to acids, and low thermal expansion.
Silicon Carbide is among the hardest of ceramics, and retains hardness and strength at elevated temperatures, which translates into among the best wear resistance. Additionally, SiC has a high thermal conductivity, especially in the CVD (chemical vapor deposition) grade, which aids in thermal shock resistance. It is also half the weight of steel.Based on this, SiC is often specified for seal faces and high performance pump parts.
Applications of SiC
Its physical hardness makes it ideal to be used in abrasive machining processes like grinding, honing, sand blasting and water jet cutting. On top of that, it has also been used in the manufacture of ceramic brake discs for sports cars, bulletproof vests, seal ring material for pump shaft sealing where it frequently runs at high speed in contact with a similar silicon carbide seal.
