This paper reviews the studies achieved by the author and his research group on functional inorganic phosphorus materials, in commemoration of the distinguished contribution award from The Japanese Association of Inorganic Phosphorus Chemistry (JAIPC) in 2019. The focus of the review is on the development both of electrically functionalized hydroxyapatite and new Na+ conduction ceramics and glass-ceramics. It is therefore to be stated here that the present review clearly differs from conventional journal-reviews which summarize related papers and collect their related references with critical comments.
