| Research Abstract |
In this project, we successfully synthesized transition-metal-free novel oxyhydridesthat has the ordered hydride ions in the K2NiF4-type structure. The oxyhydridesexhibited the hydride ion conductivity over 1500C, and conductivity value increasewith the introducing vacancies and interstitial hydride ions, Furthermore, theestablishment of synthesis method for the controlling hydride contents andarrangement in the lattice by the cation-substitution showed a guideline for thedevelopment of new materials based on oxyhydrides.
