Silit® SKD Reaction Bonded Silicon Infiltrated SiC
Material Properties
Silit® is a silicon infiltrated 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 and Siliconizing of SiC, Carbon and Si metal.
Key benefits of Silit® SKD
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 1,350°C. Silit® products can be made in large sizes and complex shapes, with excellent as-fired dimensional accuracy.
