Many compounds incorporated with hydride anion, as one of the main anionic constituent, have been reported recently, and thus it is possible to say “mixed anion” hydrides have been completely accepted. It is unexpectedly difficult to prove the presence of the hydride ion in oxides that is introduced as trace components. Nevertheless, there are material properties characteristic of these systems. They can suggest the presence of hydride ion and further serve as an evaluation method. In this talk, we will discuss about our approaches to the mixed hydrides relating to their evaluation methodologies as well as their materials properties.
