Gradular White Fused Alumina Refractory Grade , Aluminum Oxide Polishing Powder
White Fused Alumina
Raw Material And Process Of Production:
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
Applications:
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
Application:
It also can be used as materials for grinding and polishing, precision casting, spraying and coating, medium body for chemical industry, special ceramics and high-grade refractory materials,etc.
