Characteristics of spherical alumina

1. High filling density: With its large particle diameter and broad particle size distribution, realizes high-density filling for rubber and plastic and produces compounds with low viscosity and good fluidity.
2. High thermal conductivity: High filling density enables production of compounds with higher thermal conductivity and higher heat dissipation rate compared to crystalline silica.
3. Low abrasivity: Due to its Spherical shape, less-wearing of kneading machines, forming machines and dies.
Application of spherical alumina
1. Used as a ceramic material
Spherical micropowder has good compression molding and sintering characteristics, which is extremely beneficial for the production of high-quality ceramic products.
2. Used as a grinding and polishing material
Using spherical alumina as a polishing abrasive can avoid scratches.
3. Used in the petrochemical industry
In the petrochemical industry, higher and higher requirements are put forward for the pore size distribution and pore structure of the alumina carrier. The spherical alumina powder can be adjusted by adjusting the particle size configuration to control the pore size and distribution of the formed catalyst carrier particles.
4. For catalyst
The spherical alumina used directly as a catalyst can reduce abrasion and increase the service life of the catalyst, thereby reducing production costs.
5. For surface protective coating
Spherical oxide powder particles are sprayed on metals, plastics, etc., which can greatly improve the surface hardness, corrosion resistance, wear resistance and fire resistance, and are used for surface protection of machinery, tools, and chemical pipelines.
6. For luminescent materials
Spherical alumina powder has a high packing density, which can reduce the scattering of the luminous body, effectively reduce the loss of transmitted light, and thus improve the light transmittance.
7. Used in the electronics industry
Due to the excellent characteristics of spherical alumina in electrical, thermal and mechanical properties, it is widely used in the field of semiconductor electronic packaging.
