摘要

Abstract

In this paper a polyaluminum chloride solution with high Al

content was prepared and used as raw material for preparation of γ-Al

·H

O and NaOH had little effect on the alumina sample formation.The impurities of NH

Cl 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-Al

in the subsequent heating from 600℃ to 800℃.It is very interesting that Al

can be existed inγ-Al

phase even after calcinations.The results indicate that polyaluminum chloride with high Al

content is an effective material to prepareγ-Al
