The use and characteristics of spherical alumina

Overview of spherical alumina Al2O3 powder

The spherical alumina produced by the high-temperature melt spraying method has the characteristics of high sphericity and high α-phase alumina content. It shows excellent performance when used as a filler for rubber, plastics and ceramic raw materials.

Main features of spherical alumina Al2O3

1. High filling

It has high particle sphericity and wide particle size distribution, and can be used for high-density filling of rubber and plastics to obtain mixtures with low viscosity and good fluidity.

2. High thermal conductivity

Because it 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 of its spherical appearance, the wear and tear of equipment such as mixers, molding machines and molds is greatly reduced, and the service life of the equipment can be extended.

Application of spherical alumina Al2O3 powder

1. Heat sink, filler for heat dissipation substrate (MC substrate), heat dissipation grease, phase change sheet

2. Filler for semiconductor encapsulation resin

3. Silicone heat-dissipating adhesives and fillers for mixtures

4. Ceramic filter
