摘要
在100－250℃温度范围内，用水热法合成了具有层状结构的化合物LiO·2Al2O3·nH2O．通过X-射线衍射分析了其结构特征，探索了合成条件对水热反应产物的影响，用热分析研究了Li2O·2Al2O3·nH2O的脱水过程，并确定化合物的含水率，用交流复平面阻抗谱测定了化合物在不同温度时的离子电导宰结果表明，用水热法成功地合成了具有较高离子电导率的单相Li2O·2Al2O3·nH2O化合物．
The layered compound Li2O·2Al2O3·nH2O was synthesized by using hydrothermal route in the temperature range of 100-250℃, its structure was analyzed by Xray diffraction patterns. The experiments showed that the formation of Li2O·2Al2O3·nH2O was influenced by synthesis conditions, including the kind and the ratio of reaction components, temperature et al. The results of thermal analyses suggested the dehydration of its layer water and structural water at 160℃ and 230℃ respectively, and the water content was determined accordingly. The ionic conductivities of Li2O·2Al2O3·nH2O at various temperatures demonstrates its satisfactory electrical property.
