Properties and applications of alumina ball
1. Use as a ceramic material
The spherical powder has good properties of pressing and sintering, which is very beneficial to the preparation of high quality ceramic products.
2. Used as grinding and polishing material
The use of spherical alumina as polishing abrasive can avoid scratches.
3. Used in petrochemical industry
In the petrochemical industry, the pore size distribution and pore structure of alumina support have been put forward higher and higher requirements. The pore size and pore size distribution of catalyst support particles formed by spherical alumina powder can be regulated by adjusting the particle size configuration
4. Used as catalyst
Spherical alumina used directly as catalysts can reduce wear and increase catalyst life, thereby reducing production costs.
5. Used for surface protective coating
Spherical oxide powder particles sprayed on metal, plastic, etc., can greatly improve the surface hardness, corrosion resistance, wear resistance and fire resistance, used for machinery, tools, and chemical pipeline surface protection.
6. For luminescent materials
The spherical alumina powder has high packing density, which can reduce the scattering of light body, effectively reduce the loss of transmitted light, so as to improve the light transmittance.
7. Used in the electronics industry
Because of the excellent properties of spherical alumina in electrical, thermal and mechanical properties, it is widely used in the field of semiconductor electronic packaging.
