Products Description
Green silicon carbide contains more than 99% SiC, good self-sharpening, mostly used for processing carbide, titanium alloy and optical glass, also used for honing cylinder liner and fine grinding high-speed steel tools. In addition, there is cubic silicon carbide, it is a special process to produce yellow-green crystals, used to make abrasives suitable for bearing ultra-fine machining, can make the surface roughness from Ra32 ~ 0.16 microns to Ra0.04 ~ 0.02 microns at a time.
Silicon Carbide is produced by heating silica sand and a carbon source, typically petroleum coke, to high temperatures in a large, open "Acheson" furnace. The result of this high temperature process is the crystalline formation of Silicon Carbide grains, of both Green and Black coloring. The color difference is due to the purity of the silicon carbide, green SiC being higher purity due to its closer proximity to the heat source of the furnace.
