White fused alumina is a kind of middle or high level refractory material. With the eye-catching white color and the advantage of high density and low micro porosity, it can effectively improve the volume stability and the thermal shock resistance of the material. It is the mainly raw material to produce middle or high level unshaped or shaped refractory White fused alumina chemical index Na2o Sio2 40*25kg/bag put in one jumbo bag

Abrasives black fused aluminium oxide Black fused alumina, also called black fused aluminium oxide, black aluminum oxide, is a black color artificial corundum for abrasives. It's made of fusion of bauxite and reducing agent in electric arc furnace. Black fused aluminium oxide has certain content of ferro oxide and silicon oxide, which make it looks black. Black fused aluminium oxde has moderate hardness, less heat during abrasives, good strength and can be used for sand blasting, polishing, grinding of stainless steel and other non-metal surfaces. It can also be used for production of grinding wheel and cutting wheels.
