热喷涂用球形氧化铝超细粉末1微米即10000目
球形氧化铝微粉D50中值1微米2微米超细球状氧化铝粉以低钠氧化铝为原料,采用火熔法生产球形氧化铝粉。球形导致低BET表面积和高流动性。同时,球形氧化铝粉末具有高导热性和低吸油率。广泛用作电子产品中的导热填料、环氧树脂、陶瓷烧结中的隔热介质、热喷涂粉末等。
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.
