· JVASP-91703· ErH3

ErH3 is an erbium trihydride ceramic compound, a rare-earth metal hydride that belongs to the family of interstitial hydride ceramics. This material exhibits interesting mechanical properties and is primarily of research and development interest rather than established industrial production. ErH3 and related rare-earth hydrides are investigated for potential applications in hydrogen storage, advanced ceramics processing, and materials with unique electronic or thermal properties, though practical engineering adoption remains limited compared to conventional ceramic materials.
