White Fused Alumina
White Fused Alumina is produced by fusing calcined alumina in an electric arc furnace under carefully controlled conditions. It is white in color, a dense mineral and has predominantly large crystals of Alpha Alumina.
White Fused Alumina is widely used in the refractory industry as it is a very pure low iron alumina suitable for a range of applications. Specific refractory applications include high tech refractory castables, isostatic pressed refractories and pre-cast refractory shapes. The benefits of White Fused Alumina in these applications are that it has a very high alumina content, low impurities and stability at high temperatures.
