Black silicon carbide powder 10 micron

Black Silicon carbide powder is an acid pickled and water-separated powder with an extreme hardness after producing at high temperature in an electric resistance type furnace with quarts sand and petroleum coke. With even particle distribution, Black SiC powder suitable for precise polishing, lapping on hard material such as crystal, glass, marble, etc. Black silicon carbide powder will not dissolve in acid and other corrosive liquids, so it could work as an anticorrosive additive in the coating, paint.

 

Properties:

High hardness, retaining hardness and strength at high temperature.

High wear resistance.

Excellent thermal shock resistance with high thermal conductivity and low linear thermal expansion.

Good ability to withstand the strongest alkalis and acids.

 

Applications:

Ceramic products like silicon carbide ceramic seal.

Lapping, polishing.

Insulation

Cutting material such as stone, silicon wafers.

Coated abrasive tools such as sanding paper, sanding wheel, fiber disc, polishing wheel, non-woven polishing wheel

Raw material of Knife Grinder, Whetstone, oilstone, grinding stone, honing, sharpening sticks, etc.

Material of Polishing wax, polishing fluid, grinding powder, grinding fluid and so on

Wear-resisting floor and non-slip coating such as additive for epoxy resin floors.

Brake linings

Semiconductor industry.
