Top best answers to the question «Which is the highest grade of silicon carbide»

  • Silicon carbide develops a cylindrical ingot around the core, forming layers of ɑ-SiC, β-SiC, and an unreacted material on the outside. ɑ-SiC is the highest grade with a coarse crystalline structure, and β-SiC is the metallurgical grade. Based on the raw material quality, the SiC can be produced as either green or black.
  • Here below is the main chemical reaction resulting in the formation of ɑ-SiC: Silicon carbide develops a cylindrical ingot around the core, forming layers of ɑ-SiC, β-SiC, and an unreacted material on the outside. ɑ-SiC is the highest grade with a coarse crystalline structure, and β-SiC is the metallurgical grade.
