Manufacturer

Superfine

Application:

1. aluminium oxide for aluminium smelting, glass, ceramic industry etc.

2. aluminium oxide for refractory, coating, abrasive applications.

3. aluminium oxide for electric basal plate, desiccating agent, chemical and pharmacy industry, etc.

aluminum oxide property:

The product is white powder,uniform of particle size,easy to dispersion,stable of chemical performance,moderate in high temperature shrinkage and excellent sintering properties.
The product is the basic raw material in the production of heat-resisting product,abrasion-resisting products and decay resistance products such as for producing the high alumina refractories, high-strength ceramics, automobile spark plugs and  high-grade abrasive materials.

aluminum oxide property:

Soluble in water white solid. Odourless. Tasteless. Qualitative very hard. Easy absorption of moisture and not ChaoXie. Both sexes oxide, soluble in inorganic acid and alkaline solution, almost insoluble in water and the polar organic solvents. The relative density (d204) 4.0. Melting point about 2000 °C.
