Crystalline SIC

Silicon Carbide (SiC) is a synthetic mineral produced in electrical resistance furnaces by the Acheson Process. The crystals vary in colour from very pale green to black, depending on the quantity of impurities.

SiC is extremely hard and sharp, with excellent chemical properties and inert to all alkalis and acids. Its hardness is only surpassed by diamond and boron carbide.
Main properties of E-SIC 98:

  • High hardness
  • High thermal shock resistance
  • Excellent resistance at high temperatures
  • Low thermal expansion
  • Good electrical conductivity
  • Semiconductor properties
  • Si and C as alloying additive
  • High chemical resistance
  • Inert to moisture, inhibiting hydrogen accumulating reactions

Thanks to these properties and the economic advantages of using it in production, SiC is an exceptional raw material for manufacturing abrasives, refractories and technical ceramics suitable for use in extreme operating conditions.
High-quality products can only be made with high-quality raw materials. Thanks to our many years of know-how in the field of SiC production, we can maintain quality at a consistently high level by using high-quality raw materials.
