摘要
采用溶胶－凝胶法，经Ｌｉ２Ｏ掺杂，合成了Ｌｉ４ＳｉＯ４－ｘＬｉ２Ｏ（ｘ＝０．００～０．５０）离子导体材料，并用ＤＴＡ－ＴＧ，ＸＲＤ及交流阻抗等技术对样品进行了测试．结果发现：用溶胶－凝胶法可降低 Ｌｉ４ＳｉＯ４的合成温度；随Ｌｉ２Ｏ的掺入可增强基质材料的致密性并提高了其离子的导电性能，而以ｘ＝０．３０为最佳．
The Li4SiO4-xLi2O (x0. 00～0. 50) ion conductors were prepared by the Sol-Gel method. DTA-TG,XRD and A-C impedance techniques were used to study the stucture and ionic con-ductivity of samples. The experimental results showed that the Li4SiO4 sample preparing by the Sol-Gel method needed lower temperature than the sample by solid state reaction,the sinterability and ion-ic conductivity of the Li4SiO4-xLi2O (0. 00<x^0. 50) samples were increased by the dopants for Li2O.
