| 摘 要： | 用溶胶－凝胶法制备了Li4 xBxSi1-xO4-yLi2O(x=0.1-0.6;y=0.0-0.5)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Li4 xBxSi1-xO4的合成温度；随Li2O的掺入可增强基质材料的致密性并可提高其离子的导电性能。

| Abstract: | The Li4+xBxSi1-xO4 - yLi2O(x = 0. 1-0.6;y = 0.0-0. 5)ion conductors were prepared by the Sol - Gel method. DTA - TG, XRD, and A - C impedance techniques were used to study the structure and ionic conductivity of samples. The experimental results showed that the Li4 +xBxSi1-xO4 sample prepared by the Sol - Gel method needed lower temperature than the sample prepared by solid state reaction, the sinterability and ionic conductivity of the Li4+1BxSi1 -xO4 -yLi2O samples were increased by the dopant for Li2O. |
