Products Description
Silicon carbide is an inorganic substance with the chemical formula SiC,In C, N, B and other non-oxide high-tech refractory raw materials, silicon carbide is the most widely used, the most economical one, can be called gold steel sand or refractory sand.
Development history
Silicon carbide is by the American Acheson in 1891 electromelting diamond experiment, a carbide accidentally found in the laboratory, was mistaken for a mixture of diamond, so named emery, in 1893 Acheson research out of the industrial smelting silicon carbide method, that is, we often say Acheson furnace, has been used so far, with carbon materials as the core of the resistance furnace, A mixture of silica SiO2 and carbon is electrically heated to produce silicon carbide.
Material variety
Silicon carbide has two commonly used basic varieties of black silicon carbide and green silicon carbide, both belonging to α-SiC.
Black silicon carbide contains about 95% SiC, its toughness is higher than green silicon carbide, mostly used for processing low tensile strength materials, such as glass, ceramics, stone, refractory materials, cast iron and non-ferrous metals.
Green silicon carbide contains more than 97% SiC, self-sharpening is good, mostly used for processing cemented carbide, titanium alloy and optical glass, but also used for honing cylinder liner and fine grinding high-speed steel tools.
In addition, there is cubic silicon carbide, which is a special process of yellow green crystal, used to make abrade for bearing superfinishing, can make the surface roughness from Ra32 ~ 0.16 microns a processing to Ra0.04 ~ 0.02 microns.
