Product Description

                 

Product Description

 is a high-purity, fine-grained material made from that is widely used in a variety of industrial applications. It is a white crystalline powder that is typically produced through the refining of bauxite ore.
Alumina powder has a range of desirable properties, including high hardness, chemical resistance, and electrical insulation, which make it a valuable material in many industries.
It is commonly used as a raw material for the production of Ceramics,refractorier and abrasives,as well as for the manufacturing of various electronic components, such as insulators, substrates, and semiconductor components.

Application

1. Refractory materials: Because of calcined alumina after high temperature calcination, its crystals are closely arranged in six cells, with high temperature resistance;

2. Additive for thermal interface materials.

3. Wear-resistant ceramics: the crystal is closely arranged in a six-cell shape, and also has high strength and wear-resistant characteristics, widely used in ceramic wear-resistant balls and wear-resistant lining bricks;

4. Polishing and grinding, all kinds of stone to show the surface, the polishing of metal surface;

5. Ceramic whitening agent, due to high whiteness, it is added to raw materials in the production of ceramics, which has the effect of whitening, and makes the ceramics more wear-resistant and stronger;

6. Castable, calcined alumina has the characteristics of small particle size and good fluidity dispersion;

7. Artificial marble;

8. Inert ceramics, catalysts;

9. Refractory bond.
