Calcined Bauxite

Additional Details

Semi Friable Alumina is low titanium brown fused alumina. We call semi-friable fused alumina. It has higher hardness and friability ability compaired with brown fused alumina.It offers good cutting performance in fast and can be widely used in bonded abrasives for working with heat sensitive metals and alloys, soft non-ferrous metals and rubber plastic,wood etc.

Chemical Composition:

    Al2O3: 97.5MIN
    Fe2O3:0.15MAX
    SiO2:0.5MAX
    TiO2:1.5MAX

Calcined Bauxite is produced by calcining raw bauxite in a rotary, shaft or round Kiln. Calcined Bauxite is a major ingredient in making various types of Alumina Bricks and castables.
