Al2O歧化法制备微细Al2O3/Al复合粉体
Preparation of Al2O3/Al Composite Powder by Al2O Disproportionation
摘要
Abstract
Al2O3/Al composite powders were prepared by Al2O disproportionation method under vacuum condition.The composite powders were analyzed by XRD and SEM.It is indicated that the alumina content increases with the temperature increasing at a temperature ranging from 1200 to 1400 ℃, and when the condensation temperature is about 550-750 ℃, the alumina in the composite powders contained stable crystalline form and unstable crystal form.When the condensing temperature is about 1100-1300 ℃, all the alumina in the composite powder is stable.When the condensing temperature is about 550-650 ℃, the average diameter of the composite powder is less than 0.5 μm.When the condensing temperature is about 750 ℃, the aluminum is melted and the particles are agglomerated.When the condensation temperature is about 1100-1200 ℃, the average particle size of the alumina particles is less than 2 μm.At the condensation temperature of about 1300 ℃, the alumina is flakey.Therefore, by choosing the appropriate reaction temperature and condensation temperature, it can be controlled that the content, crystal and particle size of alumina in the Al2O3/Al composite powder.关键词
