· TbH2

TbH2 (terbium dihydride) is a rare-earth metal hydride ceramic compound that belongs to the lanthanide hydride family. It is primarily studied in research contexts for applications in hydrogen storage, nuclear fuel elements, and advanced metallurgical processes where rare-earth hydrides offer unique combinations of thermal and mechanical stability. The material is notable within the rare-earth hydride class for its potential in high-temperature applications and as a precursor for producing specialized rare-earth alloys, though industrial deployment remains limited compared to more conventional ceramics.
