Green Silicon Carbide Vs Black Silicon Carbide

Green silicon carbide has a purer texture and higher hardness than black silicon carbide.

Green silicon carbide vs black silicon carbide.

Black sic will contain some free silicon and carbon and thus is not as pure as green sic. In addition to the same grinding purpose as black silicon carbide it is more suitable for fine grinding of threads grinding tools and other materials and is more widely used in the grinding of hard alloy materials and diamond products. Green silicon carbide powder background. Silicon carbide is produced by heating silica sand and a carbon source typically petroleum coke to high temperatures in a large open acheson furnace.

Hexagonally shaped it breaks into very sharp particles. 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. 2 black sic is quartz sand petroleum coke in primary raw materials smelting in high temperature electric resistance arc f. Our green sic is 99 5 pure exceeding jis iso fepa standards.

Green silicon carbide manufacturing method with black silicon carbide but the raw material purity requirements are high but also in the resistance furnace at about 2200 c to form a green translucent hexagonal sic content is higher than black physical properties and black silicon carbide similar but slightly more brittle than the performance but also has good thermal conductivity. 1 their colors are different black silicon carbide short for c is black green silicon carbide short for gc is green. The result of this high temperature process is the crystalline formation of silicon carbide grains of both green and black coloring. Green sic is made from silica sand and coke and is extremely pure.
