摘要
Abstract
Anhydrous aluminum trichloride was recovered successfully from crystalline aluminum trichloride and aluminum hydroxide by high temperature reduction chlorination.The raw material pellets and products at different temperatures were characterized by FTIR,XRD,SEM to investigate the performance of two materials.The results show that both raw material pellets will be transformed into alumina at 300-800 ℃.After high-temperature chlorination,both raw material pellets can recover anhydrous aluminum trichloride.The anhydrous aluminum trichloride obtained from aluminum hydroxide raw material pellets is higher in purity,which has certain industrial prospects.关键词
