|Outline of Final Research Achievements
The purpose of this study is to obtain high quality functionalized materials by realizing insights obtained by theoretical study and ultimate analysis. The experimental scheme is based on the high pressure and high temperature process, in-situ observation under high pressure and flush-sintering at ambient pressure.
By cooperating with the researchers in theoretical and ultimate structural analysis field, we tried to figure out key factors to control superior properties in functionalized materials such as wideband gap materials, ion conductor, fluorescence materials, hard materials and heat resistive ceramics. Other major concern in this study is to realize the stability of compressed oxide and nitride ceramics under high pressure with respect to their structural phase transformations. Structural relaxation of ABO3 type oxide compounds from the high pressure phase were clarified. Unique metastable character of wrutzite boron nitride was clarified by ultimate ADF-STEM study.
