Black silicon

Black silicon carbide is the perfect material specificaly manufactured for general abrasive applications in bonded and coated abrasive tools.It is widely used for grinding nonferrous materials,finishing tough and hard materials and used as a filler in ceramic parts when processing cost is important.


Chemical Properties

HCl, HF, HNO3 and H2SO4 do not attack Silicon Carbide.
SiC has excellent deoxidation properties in iron melts. Exposed to temperatures around 1000oC Silicon Carbide is oxidized by air and oxygen. The formation of a SiO2 layer decelerates the oxidation rate.
SiC dissolves in alkaline and alkaline oxidizing melts.

Chemical Composition depending on type, size, etc. of finished SiC products, (different grit-sizes for abrasive applications, SiC splits and fine powder sizes for refractory applications) chemical composition can be slightly different. The following typical results are showing an average range of Black-SiC which is used as basic product for the different grit and split sizes:


Structure Monocrystalline
Particle shape Blocky,sharp edged
Color Black
Friability Semi-friable
Knoop hardness (100 scale) 2480
Specific gravity 3.20

Material available in all grit sizes and can be shipped in 24 hours when required from 50 metric ton inventory.
