Abrasive black silicon carbide powders are the perfect material that specifically manufactured to be used for general abrasive applications in bonded abrasive tools, lapping and polishing processes. While silicon carbide has lower hardness and abrasive capacity than diamond and boron carbide, it is widely used for grinding non-ferrous materials, finishing tough and hard materials, filling up ceramic parts when the processing cost is important.

Performance characteristics:Silicon carbide is used Quartz sand, petroleum coke (or coal coke), wood chips (salt needs to be added to the production of green silicon carbide) and other raw materials Resistance furnace It is smelted at high temperature, smelted at high temperature in a resistance furnace, black or green opaque, hexagonal crystal, Mohs hardness is 9.16-9.5。 Second only to diamond and boron carbide, the performance is brittle and sharp and has a certain degree of conductivity
Abrasive–Mainly because silicon carbide has high hardness, chemical stability and certain toughness, so silicon carbide can be used in the manufacture of consolidation abrasives, coated abrasives and free grinding, so as to process glass, ceramics, stone, cast iron and some non-ferrous metals, cemented carbide, titanium alloys, high-speed steel tools and grinding wheels.

White corundum is made of high-quality aluminum oxide powder as raw material, which is crystallized by electromelting. High purity, good self-sharpening, acid and alkali corrosion resistance, high temperature resistance, stable thermal performance, its hardness is slightly higher than brown corundum, slightly lower toughness, high purity, good self-sharpening, strong grinding ability, small calorific value, high efficiency, acid and alkali corrosion resistance, high temperature thermal stability. It is used to make abrasives, suitable for grinding fine-grained abrasives such as high carbon steel, high speed steel and stainless steel, and can also be used for precision casting and advanced refractory materials.

Black Silicon Carbide is produced by a process involving the electrochemical reaction of silica(SiO2) – in the form of quartz mixed with Carbon(C) in the form of raw petroleum cok. The stoichiometric mixture is reacted in an electrical resistance furnace at a temperature up to 2500℃ to yield high quality crystals.
Black Silicon carbide powder is aci pickled an water separated powder with an extreme hardness after producing at high temperature in an electric resistance type furnace with quarts sand and petroleum cok.
