Emery general term, silicon carbide, also can be brown fused alumina, also can be a black corundum (SiC, also known as silicon carbide), or white corundum.Pure is a colorless crystals, density of 3.06 ~ 3.20.Hardness is very big, is about 9.5 degrees Morse, generally is colorless powder particles, after grinding, can be used as a polishing powder, polishing paper could be prepared, but also grinding wheel and strop friction surface.By the sand and the right amount of carbon in electric furnace to strengthen heat.
emery characteristics
Emery inside contain no cause silicosis free silicon harmful substances, do not contain toxic or radioactive pollution of heavy metals, because the product density is larger, seldom produce dust, effectively guarantee the operator's health, in addition, the characteristics of the low consumption and recycled products can greatly reduce the waste after the products use processing and cost.
