In the temperature range of 100-250 ℃, the compound LiO · 2Al2O3 · nH2O with layered structure was synthesized by hydrothermal method. The structure of Li2O · 2Al2O3 · nH2O was studied by means of X-ray diffraction. The influence of synthesis conditions on the hydrothermal reaction products was explored. The dehydration of Li2O · 2Al2O3 · nH2O was studied by thermal analysis and the moisture content of the compound was determined. The results of the ionic conductivity measurements of the compounds at different temperatures show that the single-phase Li2O · 2Al2O3 · nH2O compounds with higher ionic conductivity have been successfully synthesized by hydrothermal method.
