摘要/Abstract

摘要： In this paper a polyaluminum chloride solution with high Al₁₃ content was prepared and used as raw material for preparation of γ-Al₂O₃₃·H₂O and NaOH had little effect on the alumina sample formation.The impurities of NH₄Cl and NaCl in solution can be removed through repeated washing by EDX analysis.Calcination temperature had a significant effect on alumina crystal phase.The alumina sample can transform completely toγ-Al₂O₃ in the subsequent heating from 600℃ to 800℃.It is very interesting that Al₁₃ can be existed inγ-Al₂O₃ phase even after calcinations.The results indicate that polyaluminum chloride with high Al₁₃ content is an effective material to prepareγ-Al₂O₃.
