Mineral information

Brown Fused Alumina is a dense material produced from bauxite raw material. The end product has a low iron content making it particularly valuable in refractory applications.

White Fused Alumina is produced by fusing calcined alumina. It is white in colour, a dense mineral with predominantly large Alpha Alumina crystals. With a high purity, high melting point, and a superior hardness, this product is well suited to refractory and ceramics industries.
