Spherical alumina: characteristics
1. High filling: Due to its large particle size and particle distribution, this product produces compounds of low viscosity.
2. High thermal conduction: The high filling density of the compound allows it to have higher thermal conduction and heat dissipation rates compared with crystalline silicon.
3. Spherical shape reduces abrasivity. This means less wear and tear on machines such as kneading machines.
Application of spherical aluminum
1. Use as a ceramic material
Micropowder with spherical particles has good compression-molding and sintering qualities, which makes it ideal for producing high-quality ceramics.
2. It is used as a material for grinding and polishing
You can prevent scratches by using spherical aluminum oxide as a polishing material.
3. It is used in the petrochemical industries
In the petrochemical industries, the requirements for pore size distribution as well as pore structure are increasing. To control the particle size distribution, it is possible to adjust the particle size configuration of the spherical aluminum powder.
4. Catalyst
The use of spherical aluminum as a catalyst directly can reduce abrasion while increasing the lifespan of the catalyst. This will lower the production costs.
5. For surface protective coating
Surface protection for machinery, tools, chemical pipelines, and equipment is achieved by spraying spherical powder particles. These can significantly improve surface hardness, corrosion and wear resistance.
6. Luminescent materials
Alumina powder spherical has a high density which reduces the scattering and loss of light.
7. Electronics industry
The excellent properties of spherical aluminum in terms of electrical, thermal, and mechanical properties make it a popular choice for electronic semiconductor packaging.
