Brown fused alumina produced by our company is refined at high temperature for a long time, which makes the chemical composition fully reduced for low carbon, low iron and low silicon.
It is characterized by high purity, good crystallization, small coefficient of expansion, good fluidity, large bulk density, the resistance to high temperature, scour and corrosion.
It is the best aggregate and filler material for corundum refractories without bursting, pulverization or cracking in manufacturing.
