Product introduction 

High purity aluminium oxide/alumina powder
Aluminum Oxide (99.99%)

High purity White aluminum oxide is a kind of middle or high level refractory material. with the eye-catching white color and the advantage of high density and low micro porosity, it can effectively improve the volume stability and the thermal shock resistance of the material. It is the mainly raw material to produce middle or high level unshaped or shaped refractory material. It is applied to the unshaped refractory materials, such as refractory carstables for ladles, middle or high level iron runner casting material, gunning refractory and fabricate parts ect. It also can be used to kinds of corundum products, such as corundum bricks, corundum, mullite corundum, refining corundum perforated bricks, overall blowtorch and combined nozzle, side ceiling of the high temperature kiln, ect. All in all, it is widely used in steel, cement, ceramics, grinding material and petrochemical industries. 

White Aluminium oxide, with even size distribution, excellent chemical compositions make the good hardness and toughness.
