Normal Soda Coarse Aluminas

Calcinedaluminas are widely used in refractories and in the ceramic industry Specific properties include extreme hardness, refractoriness, high mechanical strength and resistance to wear abrasion, chemical attack and corrosion. These are used as feed material for fused alumina, refractory aggregates, etc. 

HINDALCO coarse alumina grades are white crystalline powders which are predominantly alpha alumina of high chemical purity and consistent physical properties. These products have excellent grindability properties.
