Green silicon carbide has a purer texture and higher hardness than black silicon carbide.
Green silicon carbide vs black silicon carbide.
Green sic is made from silica sand and coke and is extremely pure.
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.
Black will range in purity from 97 99 pure depending on grit size.
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.
Hexagonally shaped it breaks into very sharp particles.
Green silicon carbide powder background.
In terms of its color is green so named green silicon carbide.
Green silicon carbide used in the manufacture of raw materials such as black silicon carbide production is roughly the same in addition to industrial salt as a reagent and promoter reaction in the resistance furnace.
Black sic will contain some free silicon and carbon and thus is not as pure as green sic.
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.
Silicon carbide is produced by heating silica sand and a carbon source typically petroleum coke to high temperatures in a large open acheson furnace.
