We have carried out the studies on the synthesis, structure and properties of the rare earth oxide-containing ceramics, which cover the projects of (1) glass and glass-ceramics of Na^+-Ion conducting silicophosphates (Narpsio) , (2) Stabilized zirconia and cerai ceramics, and (3) proton conducting hydroxyapatite and its coating methods.In project (1), we successfully produced glass-ceramics of fast sodium ion conductors, which are invaluable for application of Na/S secondary batteries. The synthetic method, conduction mechanism, and other fundamental properties were established.In project (2), rare earth oxide-stabilized zirconia and ceria ceramics were developed as high temperature pH and oxygen sensors. For this research, we have performed the electrophoretic lamination technique which enabled to insert thin zirconia layr into conducting ceria ceramics.In project (3), we investigated the proton conduction in ceramic hydroxyapatite, which is the well-known bimedical material. Thin film methods were also developed for this prupose. Additionally, we founf that the use of polarization property of the material is effective for crystal growth.

本论文对含稀土氧化物陶瓷材料的合成、结构和性能进行了研究，包括：（1）Na^+离子导电硅磷酸盐玻璃和微晶玻璃（Narpsio）;（2）稳定氧化锆和陶瓷;（3）质子导电羟基磷灰石及其涂层方法。我们成功地生产了钠离子快导体玻璃陶瓷，这对钠/硫二次电池的应用是非常宝贵的。确立了其合成方法、导电机理等基本性能。项目（2）开发了稀土氧化物稳定的氧化锆和氧化铈陶瓷作为高温pH和氧传感器。在本研究中，我们采用电泳层压技术，在导电氧化铈陶瓷中插入氧化锆薄层。在项目（3）中，我们研究了生物医用材料羟基磷灰石陶瓷的质子传导。薄膜方法也被开发用于此目的。此外，我们还发现利用材料的偏振特性是晶体生长的有效途径。
