· JVASP-18401· MnH

Manganese hydride (MnH) is an intermetallic compound combining manganese metal with hydrogen, belonging to the family of metal hydrides. This material is primarily of research interest rather than established in high-volume industrial production, with potential applications in hydrogen storage, energy conversion systems, and advanced functional materials where hydrogen incorporation into metallic lattices offers unique property combinations.
