Spherical alpha-Al2O3 powder Applications

Spherical alpha-Al2O3 powder Applications is a special form of alumina powder. It features with its excellent thermal conductivity, high specific surface area, and insulation properties. There are several application and usage field of it:

1. Thermal interface materials: such as thermal conductive silicone gaskets, thermal conductive silicone grease, thermal conductive sealant, thermal conductive tape, battery thermal conductive film, etc.
Spherical alumina has high thermal conductivity and can be used to make thermal pads or silicone gel, which can transfer heat from the heating area to the heat dissipation area and reduce the local temperature of the heating area. It can also improve insulation, shock absorption, and sealing performance.

2. Thermal conductive engineering plastics: such as LED lampshades, switch housings, electronic product housings, electrical product heat dissipation components, etc.

3. Thermal conductive aluminum based copper-clad laminates: high-power LED circuit boards, power circuit boards, etc.

4. Filter with alumina ceramic membrane tube.

5. Thermal spray coating, wear-resistant coating, wear-resistant coating. Spherical alumina micro powder used for coating can improve the material’s wear resistance, corrosion resistance, high temperature resistance, oxidation resistance, and electromagnetic wave resistance.
