摘　　要：锆酸钙基材料具有优良的热、机械、发光、介电性能,是先进的耐火、发光、铁电材料。自1991年Iwahara等发现锆酸钙基材料在高温下具有质子导电性以来,锆酸钙基电解质陶瓷的研究取得重大进展。本文结合本实验室的研究分别从材料制备、陶瓷烧结、质子传输机理及影响质子传输的因素等4个方面就20年来锆酸钙基质子导体材料的研究进展进行了综述,并对其未来发展进行了展望。CaZrO3 based materials have already been extensively applied as refractories, luminescent materials, as well as ferroelectric ones due to their physical and chemical stability, mechanical strength and excellent fluorescent and dielectric properties. Since the discovery of stable proton conductivity at a relatively high temperature by Iwahara in 1991, much progresses on CaZrO3 based materials have been made during the past 20 years. This paper intends to review the progresses, as well as some researches of our group in this field, including powder synthesis method, ceramic sintering process, proton transfer mechanism and the major factors influencing proton conductivity. The problems and further orientation in this research area are also discussed.
