Brown Fused Alumina Introduction:

Brown Fused Alumina belongs to the group of electro-corundum. It is also be called brown aluminum oxide, brown corundum or brown fused aluminum oxide. It is produced by the smelting of calcined bauxite in an electric arc furnace at temperatures more than 2000°C. Brown fused alumina DIN fraction sand can be used in refractory materials and anti-slip road surface preparation.
