| Research Abstract |
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.
