· JVASP-39485· ReH3

ReH3 is a rare-earth hydride ceramic compound belonging to the metal hydride family, where ReH3 likely denotes a rare-earth element combined with hydrogen in a 1:3 stoichiometric ratio. This material is primarily of research interest in materials science and solid-state chemistry, with potential applications in hydrogen storage, catalysis, and advanced ceramics development. Its high density and hydride composition make it a candidate material for studying hydrogen interactions in ceramic systems, though industrial adoption remains limited and the material is better understood within academic and experimental contexts rather than in widespread commercial use.
