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.

Dense mineral

Low iron content

Non-hazardous

Non-toxic

Stable Mineral

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.
