White Fused Alumina

Product Information
White Fused Alumina( also known as white corundum or white aluminium oxide)is a high purity, synthetic mineral, and produced in the electric arc furnace by fusing calcined alumina. It is white color, a dense mineral and owns large crystals of Alpha Alumina. It has a high refractoryness and is extremely hard and resistant.
