| Outline of Final Research Achievements |
"Hydrothermal Reaction" is an academic term used in geology for reactions inside the earth, and is a reaction mainly using water as a solvent under high temperature and high pressure condition. Inside the earth mineralization and crystal growth occur by hydrothermal reactions and they have been used for synthesis and crystal growth for inorganic compounds. In this study, the following results were obtained in the synthesis of inorganic compounds using hydrothermal reaction. (1) Discovery of new bismuth oxide and its characterization, (2) Synthesis of pyrochlore-type niobium and tantalum oxides and antibacterial properties of their silver ion-exchanged derivatives, (3) Discovery of new alkali metal niobium and tantalum fluorides and fluorescent properties of their Mn4+ doped derivatives
