主　　题：γ-Al2O3 polyaluminum chloride preparation Al13 

摘      要：In this paper a polyaluminum chloride solution with high Al13 content was prepared and used as raw material for preparation ofγ-*** texture and crystalline phase of the prepared alumina samples were characterized by energy dispersive X-ray spectroscopy(EDX) ,X-ray diffraction,transmission electron microscope(TEM) and nuclear magnetic resonance(NMR) *** effects of alkaline solution and calcination temperature were *** results showed that alkaline solution including NH3·H2O and NaOH had little effect on the alumina sample *** impurities of NH4Cl and NaCl in solution can be removed through repeated washing by EDX *** temperature had a significant effect on alumina crystal *** alumina sample can transform completely toγ-Al2O3 in the subsequent heating from 600°C to 800°*** is very interesting that Al13 can be existed inγ-Al2O3 phase even after *** results indicate that polyaluminum chloride with high Al13 content is an effective material to prepareγ-Al2O3.
