Product Feature of Silicon carbide FEPA 220mesh Black color

  • High purity, the purity of black silicon carbide after pickling can reach 99%. The production process of black silicon carbide powder is hydraulic classification, with less impurities and high purity.
  • Superior oxidation resistance and chemical stability: when heated to 1000 ℃ in the air, silicon carbide only oxidizes on the surface, forming a layer of silicon dioxide film, which can protect silicon carbide material from oxidation. When heated to above 1627 ℃, the oxidation resistance of silicon carbide will decline rapidly.
  • High hardness: Mohs hardness of black silicon carbide is 9.2-9.3, slightly lower than that of green silicon carbide.
  • The toughness of black silicon carbide is higher than that of green silicon carbide.
  • The packing density is high, and the black silicon carbide particles produced by the shaping process are more rounded.
  • It has high cleanliness and is washed twice after crushing, reducing the dust in the abrasive.
