Fused Alumina

Fused Alumina is made in an electric arc furnace by passing a current between vertical carbon electrodes. The heat generated from this procedure melts the alumina feedstock.

Fused alumina packaging

Our Fused Alumina product range is available in 25kg paper sacks, 1000kg bulk bags, or as bulk as standard.

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.
