Silicon Carbide grit

Silicon Carbide grit

1.Green and Black silicon carbide

2.SiC: 98%min refractory

        Silicon Carbide grit is a non-metallic, non-mineral product generated from quartz sand (SiO2) and anthracite coal or petroleum coke(C) under temperature as high as 1,800 degrees Celsius. It can be clarified into black and green silicon carbide depending on the variance of its raw material. Due to its high hardness, low expansion coefficients, ness and good thermal conductivity. It is widely used in abrasives, abrasive cutting electronic products, refractories, special ceramics, foam ceramic, paint, plastics and rubber modified, auto parts, military aviation , steelmaking deoxidation, etc.
 

Advantages

(1) Large melting furnace, longer melting time, lead to more crystallization, bigger crystals, higher purity and less impurities.

(2) Good hardness, longer life.

(3) Chemical washed and water washed, good cleanness.

(4) Special treated products get higher purity, better toughness, and better grinding effect.
