Corrosion and high temperature resistant black silicon carbide

Black silicon carbide (BLACK SILICON CARBIDE) is a non-metallic mineral abrasive that is fused with quartz sand (the main component is SiO2) and anthracite (the main component is C) at a high temperature above 1800 degrees Celsius. Between corundum and diamond, the mechanical strength is higher than corundum, brittle and sharp. It has the characteristics of high hardness, small expansion coefficient, brittleness, and good thermal conductivity.

Between corundum and diamond, the mechanical strength is higher than corundum, brittle and sharp. It has the characteristics of high hardness, small expansion coefficient, brittleness, and good thermal conductivity.
It is widely used in abrasives, electronic product grinding, refractory materials, special ceramics, foam ceramics, coating and plastic modification, auto parts, military aviation, Deoxidizer for steelmaking, etc.


Three elements of high-grade abrasive

1. High cleanliness

Put the abrasive into a glass and add water to stir. The aqueous solution is clear and transparent, with a small amount of suspended matter.

2. High bulk density, low particle roundness value

The grinding efficiency is high, and the surface finish of the workpiece is good.

3. High purity:

Detailed use

1. Used for abrasives such as emery cloth, sandpaper, cutting sheet, etc. 

2. Used on the surface of the wear-resistant layer, such as the wear-resistant layer on the surface of the skateboard, and the wear-resistant track.

3. For sandblasting metal, tank, gear surface, excellent sandblasting effect
