Black Silicon Carbide For Sandblasting And Refractory
Products Introduction
Black silicon carbide is quartz sand, petroleum coke and wood chips as the main raw material, in the resistance furnace by high temperature smelting.Black silicon carbide has a Mohs hardness of 9.15 and a relatively high hardness. It is suitable for precision grinding of hard glass.
Advantages
(1) Special treated products get higher purity, better toughness, and better grinding effect
(2) higher purity and less impurities
(3) Chemical washed and water washed good cleanness.
(4) Good hardness,Corrosion resistance
