Silit® SK Reaction Bonded SiC

Material Properties

Silit® is a reaction bonded Silicon Carbide material, consisting of 85% SiC and 15% Si metal.

Silit® products are branded as Silit® SK or Silit® SKD depending on the manufacturing process. Both are made by Reaction Bonding of SiC, Carbon and Si metal,

Key benefits of Silit® SK

Silit® products are lighter than Sintered SiC, yet offer high thermal conductivity, little to no apparent porosity, high mechanical strength, oxidation resistance and maximum service temperature of 13500C. Silit® products can be made in large sizes and complex shapes, with excellent as-fired dimensional accuracy.
