Reaction Bonded Silicon Carbide (RBSiC)

Reaction Bonded Silicon Carbide (RBSiC)

Reaction bonded silicon carbide (RBSiC), also known as siliconized silicon carbide or SiSiC as well as Reaction Sintering, is a type of silicon carbide that is manufactured by a chemical reaction between porous carbon or graphite with molten silicon. Due to the left-over traces of silicon, reaction bonded silicon carbide is often referred to as siliconized silicon carbide, or its abbreviation SiSiC.

The reaction bonded silicon carbide ceramic (RBSIC) has various excellent characteristics such as high hardness, high decomposition temperature, high thermal conductivity, low expansion, corrosion resistance etc., and has been widely used in the fields of machinery, petroleum, automobile industry and so on.

Application of Reaction bonded silicon carbide:

  • Mechanical seals and vanes
  • Wear parts and thrust bearings
  • Kiln furniture and support components
  • Precision components
