Introduction
Silicon carbide / Sic micron whisker (Sic-w) has the good chemistry stability, low heated expansion, high efficiency of heat conductivity, electrical resistance comparing with metal being in the opposite direction, very hard and the level over 9.5 of Moss's.
Sic (silicon carbide) resists heat, grinding & crushing, especially in resisting hot shock wave, corrosion and radiation.
The shape of Beta Sic is crystallized as diamond. Harder than α Sic reaching the level 9.5 of Moss's, good measure of tensile strength, best efficiency for electric current.

Application
Abrading cemented carbide, optical glass, ceramics and other hard and brittle nonmetals materials. At the same time, it not only can consolidate and paint the abrasive tools, but also can cutting and polishing freely etc. Its suitable for processing of cast iron, cemented carbide, titanium alloys, high speed steels etc. Meanwhile, it can also Polish the nonmetal materials such as glass, ceramics, stones materials, semiconductor, agates and high-grade jades and jewels as well as manufacturing high-grade refractory materials, engineering ceramics, heating element and heat components.
Characters
Black Silicon Carbide is produced basically in the same way with the black silicon carbide, except the different requirements of raw materials and manufacturing process. Black Silicon Carbide presents black & semi-transparent, its hardness and purity are all superior to black Silicon Carbide. Green Silicon Carbide have high rigidity with strong cutting force, steady chemical property, and good capacity of heat-transmission.
