Product Description
White aluminum oxide microsphere 2um 99.9% purity
Description:
Spherical alumina powder is produced from low soda aluminum oxide aluminum oxide by fire fusing process. The sphere shape leads to low BET surface area and high flowability. In the meantime, spherical alumina powder is of high thermal conductivity and low oil absorption rate. It is widely used as thermal conductive filler in electronics, expoxy resin, thermal insulating media in ceramic sintering, thermal spaying powder, etc.
White aluminum oxide microsphere 2um 99.9% purity Characteristic:
1. High Al2O3 purity more than 99.9%. Low Na2O content less than 0.1%.
2. High spherical rate, good flowability without damage for grinding.
3. Low oil absorption rate make it suitable for filler material.
4. Low BET surface area and low Viscosity mixed with resin.
5. Higher thermal conductivity than angular aluminum oxide.
