Synthesizing Process of Prepared Ultrafine Alumina Powder by Ammonia Precipitation Method
Abstract:
In this paper, ultrafine alumina powder was prepared by Ammonia PrecipitationMethod used Al(NO3)3·9H2O as aluminum source. The effects of synthesizing temperature,compounds reaction time on phase formation,morphology particlesizes were investigated. The results shows thatγ-Al2O3 can be prepared at 900°C for 2h by the Al2O3 precursor using AmmoniaPrecipitation Method. And α-Al2O3 with stable crystal structure can be got at 1100°C for 2h.
