Erbium hydride (ErH) is an intermetallic ceramic compound combining the rare-earth element erbium with hydrogen, belonging to the family of rare-earth hydrides. This material is primarily of research and specialized industrial interest, used in applications requiring high-temperature stability, neutron absorption, or unique optical/magnetic properties characteristic of erbium-based systems. ErH and related rare-earth hydrides are explored for nuclear shielding, hydrogen storage research, and as precursors for advanced ceramic and metallic materials synthesis, though commercial deployment remains limited compared to conventional structural ceramics.
