· JVASP-91932· TbH3

TbH3 is an intermetallic hydride ceramic compound combining terbium with hydrogen, belonging to the rare-earth hydride family. This material exists primarily in research and development contexts rather than established industrial production, with potential applications in hydrogen storage systems, advanced ceramics, and specialized electronic or magnetic devices where rare-earth elements provide functional benefits. The terbium hydride system is notable for its unique crystal structure and properties that emerge from the rare-earth–hydrogen bonding, making it of interest to materials scientists exploring next-generation functional ceramics and energy storage solutions.
