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.

Brief information
WFA white emery sand grit 36 was made from the high quality alumina by melting above 2000 in the electric arc furnace and cooling.
WFA white emery sand is white with the main crystal phase alpha-Al2O3.
The WFA white emery sand produced in titling electric arc furnace has the advantage of high bulk density and low porosity and the volume stability and thermal shock resistance can be improved.
