摘要
采用溶胶－凝胶法制备了稀土氧化物ＲＥ２Ｏ３（ＲＥ＝Ｄｙ，Ｈｏ，Ｅｒ，Ｙ）掺杂的Ｌｉ２ＳｉＯ３离子导体材料，并用ＤＴＡ、ＸＲＤ、ＴＥＭ及交流阻抗仪等技术对样品的结构、形貌、粒径及离子导电性等进行了观察和测试。结果发现，０．１ＲＥ２Ｏ３的掺入可提高Ｌｉ２ＳｉＯ３的离子导电性。
The Li2SiO3 ion conductor doped with RE2O3 (RE=Dy,Ho,Er,Y) were prepared by sol-gel method.DTA, XRD, TEM and A-C impedance techniques were used to study the phase structure, powder shape,and ionic conductivity of samples. The results demonstrated that they were consisted of two phases:Li2Sio3 and RE2O3, and ionic conductivity of Li2SiO3 was increased and optimized by the dopant of0.1 RE2O3.
