The Properties And Application of Spherical Alumina

What exactly is Spherical Alumina, and how can it help you?

Spherical aluminum refers to a form of alumina having a spherical shape. The type of crystal phase it has is called -alumina.

Why should we emphasize the “spherical” shape? The reason is that the area of application for alumina products can become too large, and performance in many areas of application is closely tied to the size and morphology of raw powder particles. Spherical powder particles can have different shapes but have regular morphology. A smaller specific area, greater bulk density, better fluidity and a higher level of application performance.

Spherical aluminum is one of the finer chemical products in the alumina family. It is capable of compress molding and sintering ceramics with outstanding quality. The regular morphology is also good for grinding and polishing materials. In the petroleum industry it can be used to catalyze superfine, spherical, and aluminum powder. This can decrease wear and prolong the product’s service life, thus lowering production costs.
Spherical Alumina can be used in the following:

1. As a ceramic material
Spherical Allumina exhibits excellent compression molding characteristics and sintering capabilities, making it a great choice for high-quality ceramic products.
2. It is used as a grinding or polishing material
You can avoid scratches using spherical-alumina polishing abrasives.

3. It is used in the petrochemical sector
Higher requirements for the distribution of pores and the structure of the aluminum carrier are being made in the Petrochemical Industry. You can adjust the configuration of the particles to alter the size distribution and size of the spherical Alumina Powder.

4. To act as catalyst
Directly using spherical aluminum as a catalyst may reduce abrasion, increase service life and lower production costs.

5. For surface protective coating
Spherical powder particles of spherical oxide are spray on metals and other plastics. This can significantly improve the surface hardness and corrosion resistance as well as wear resistance and fire resistance. They are also used to protect machinery and tools.

6. Materials that are luminescent
Alumina powder spheres have a very high bulk density. This can help reduce scattering from the luminous bodies, reduce lost light and improve light transmission.

7. This is used in the electronic industry
Because of the outstanding characteristics of spherical aluminum in terms of electrical, thermal, mechanical properties it is extensively used in the area of semiconductor electronic packaging.
