摘　　要：纯二氧化锆掺杂了与锆离子半径相近的低价阳离子后,会产生较多氧空穴,可以实现离子导电。其中Y2O3掺杂ZrO2基电解质材料有着优越的离子传导能力,它已经被广泛的应用到传感器和固体电解质上。介绍了Y2O3掺杂ZrO2基电解质材料导电的机理,简述了YSZ材料以及多元掺杂的ZrO2基电解质材料的研究进展。Doping cation with low valences, whose radius is close to that of zirconium in the pure zirconia, the ionic conductivity can be realized by much oxygen vacancies. Electrolyte materials of ZrO2 base doped yttria have ascendant conductive property of oxygen ions, which have already extensively application in sensor and solid electrolyte. This paper introduced conductive mechanism of ZrO2 base electrolyte materials doped Y2O3. At the same time, it narrated the development of YSZ material and multi-element doped ZrO2 base electrolyte materials briefly.
