· JVASP-139057· Mg2HSe

Mg₂HSe is a metal hydride selenide ceramic compound combining magnesium with selenium and hydrogen, representing an emerging class of mixed-anion materials studied primarily in materials research rather than established industrial production. This compound belongs to the family of alkaline-earth metal chalcogenide hydrides, which are of interest for hydrogen storage, ionic conductivity, and photocatalytic applications due to their layered crystal structures and tunable electronic properties. Engineers would consider this material for next-generation energy storage systems or catalytic devices where the combined effects of hydrogen incorporation and selenium's semiconducting properties offer potential advantages over conventional single-anion ceramics.
