Black Silicon carbide powder is acid pickled water separated powder with an extreme hardness after producing at high temperature in an electric resistance type furnace with quarts sand and petroleum coke. 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

Grinding wheel uses silicon carbide 30# 36# 46# 60# black silicon carbide 98.5% Black silicon carbide grain is produced in an electric-resistance type furnace through fusing quartz sand and petroleum coke with high temperature. Its hardness is between fused alumina and diamond. It has higher mechanical intensity than fused alumina.Black silicon carbide micro powder for

It is used for the bicycle, motorcycle, sewing machine, and clock parts. Light ornament, plastic and hardware polishing, and also applicable to the sand blasting. It is the production materials: manufacturing resin-cutting slice, edges and corners grinding and coated abrasives. The black corundum particle and micro powder are suitable for stainless steel work piece polishing

Black silicon carbide for bonded coated abrasives tools Black silicon carbide is produced from quartz sand and high quality anthracite/petroleum coke under high temperature in and electric resistance furnace. It looks black and has a microhardness of 2800-3300kg/mm2. Abrasive tools made of it, are fit to grind metals and non-metals materials of low tensile strength,

Difference and similarities between black silicon carbide & green silicon carbide 1.Their colors are different, black silicon carbide ( short for C) is black, green silicon carbide (short for GC) is green. 2.Black SiC is quartz sand, petroleum coke in primary raw materials, smelting in high temperature electric resistance arc furnace. Green SiC is made

Black silicon carbide factory Black silicon carbide is made from quartz sand and smokeless acetylene as the main raw material. It is made via light resistance from hydro metallurgical, it is black opaque body hexagonal crystal and MOHS—hardness the 9.15, which is after diamond and boron carbide with crisp and sharp performance and certain degree
