Middle Heat Treatments Brown Fused Alumina
This product is quenched in low temperature heating during processing. It has lots of excellence such as:
The inner pressure of B.F.A, which is caused during processing, is complete removed;
The single crystal of B.F.A is increased and polycrystal of B.F.A is decreased;
Both TiO and TiO3 are changed to TiO2 during calcining, thus, the sharpness and colour of products is improved, the magnetic material is reduced.
This kinds of grains are the best material to produce high-loading grinding wheels, bonded abrasives, coated abrasives and sand blasting.
