    Silicone carbide SiC for metallurgy usage

    Silicon carbide for metallurgy is used for alloying, deoxidation, inoculation of grafitic cast irons and steels. Silicon carbide is one of the important Silicon carriers in nowadays metallurgy.

    Property of SIC:
  • SiC is nearly without any foreign matters
