Development of New High-Performance Ceramics

This laboratory is engaged in the study mainly of functional materials such as dielectric ceramics, ionic conducting ceramics and thermoelectric ceramics to contribute the energy and environment issues.

A main object is to develop high-performance multi-functional ceramic materials and to obtain principles to improve the performance of materials. The phase separation process during the solid state sintering or solidification of melted ceramics,and the codeposition process in multi-component MOCVD or plasma-assisted sputtering are employed to synthesize new functional ceramic materials.
