Product Description

Calcined Alumina ,aluminum oxide

Appearance: White powder

Material: A-AL203

Grade Standard: Industrial Grade

1. Stable crystal form
2. High hardness
3. Good resistance to abrasion
4. High mechanical strength
5. High melting point 6. Excellent electric insulating property
7. Outstanding resistance to corrosion

Calcined Alumina is white powder, good flowability, performance stability, hardly soluble in acid and alkali, excellent sintering property. It used as high quality material for aluminous refractory, sintering coroundum and ceramics.

It's wildly used in the production of heat-resisting, wear-resisting, corrosion-resisting products, such as high alumina refractory products, strong ceramics, high grade abrasive, electromagnetic equipments, etc.

Note: Particle size can be made as your requirements.
