Recently, Lacorre and his coworker discovered that La_2Mo_2O_9 as a new type of oxide-ion conductor has higher oxide-ionic conductivity than that of conventional yttria stabilized zirconia. However, up to now, most of the literatures on La_2Mo_2O_9 and doped La_2Mo_2O_9 reported mainly concerned with the characterization of structure and phase transformation, there has been no detailed work with respect to the conduction property on them.

最近，Lacorre等人发现新型氧离子导体钼酸镧(La_2Mo_2O_9)复合氧化物具有比传统的氧化钇稳定的二氧化锆更高的氧离子电导率，但至今有关La_2Mo_2O_9基氧化物的文献侧重于其结构、相变的报道，对其导电性能及其变化规律的研究报道较少。

The material of the invention has lower heat conductivity and higher coefficient of thermal expansion compared to the traditional zirconium oxide which is solidified by 7-8% yttrium oxide.

与目前普遍使用的7～8％氧化钇稳定的氧化锆相比，该材料具有低的热导率和高的热膨胀系数。

Because of the adulteration of rare earth ion and the lamellar structure of the calcium and titanium mine, the material has lower heat conductivity and higher coefficient of thermal expansion compared to the zirconium oxide which is stabilized by 7-8% yttrium oxide.

由于稀土离子的掺杂及其自身的层状钙钛矿结构，该材料与目前普遍使用的7～8％氧化钇稳定的氧化锆相比具有更低的热导率和更高的热膨胀系数。
