Spherical aluminum oxide produced by the high-temperature melt spraying method has the characteristics of high sphericity and high content of α-phase aluminum oxide. It shows superior performance when used as a filler for rubber and plastics and as a raw material for ceramics.
Spherical Aluminum oxide Powder Properties
1. High filling
Spherical aluminum oxide has high sphericity and wide particle size distribution. It can fill rubber and plastics with high density, and obtain a mixture with low viscosity and good fluidity.
2. High thermal conductivity
Because spherical aluminum oxide can be filled with high density, compared with crystalline silicon powder, a mixture with high thermal conductivity and good heat dissipation can be obtained.
3. Low wear
Because the appearance of spherical aluminum oxide is spherical, the abrasion of equipment such as kneaders, molding machines and molds is greatly reduced, and the service life of the equipment can be prolonged.
Spherical Aluminum oxide Powder Applications
1. Used as a ceramic material
Spherical aluminum oxide 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 aluminum oxide 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 aluminum oxide carrier. The spherical aluminum oxide powder can be adjusted by adjusting the particle size configuration to control the pore size and distribution of the formed catalyst carrier particles.
4. Used in catalysts
The spherical aluminum oxide used directly as a catalyst can reduce abrasion and increase the service life of the catalyst, thereby reducing production costs.
5. Used for surface protective coating
Spherical aluminum oxide powder sprayed on metals, plastics, etc. can greatly improve the surface hardness, corrosion resistance, wear resistance and fire resistance, and is used for surface protection of machinery, knives, and chemical pipelines.
6. Used for luminescent materials
Spherical aluminum oxide 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 aluminum oxide in terms of electrical, thermal and mechanical properties, it is widely used in the field of semiconductor electronic packaging.
