| Research Abstract |
New material functions have been explored by employing a methodology such that highly reducing chemical species are incorporated into microstructure of oxide mineral crystals that are composed of abundant elements. Fully hydride (H^-) ion-incorporated mayenite (C12A7) was synthesized at the first time, and general detection method for H^- ion was established. In electron (e^-)-incorporated C12A7, we elucidated the origin of metallic conductivity, established a general quantification method for e^-, and demonstrated its function as anti-oxidation powder. Incorporation of H^- and e^- was also realized in Sr-substituted maynite.
