· JVASP-79470· LaH3

Lanthanum trihydride (LaH₃) is an ionic ceramic compound belonging to the rare-earth metal hydride family, formed by the reaction of lanthanum metal with hydrogen. This material is primarily of research and specialized industrial interest rather than mainstream engineering use, with applications in hydrogen storage systems, advanced catalysis, and as a precursor for producing other lanthanide compounds and materials. LaH₃ is notable for its potential in hydrogen economy technologies and metal hydride research, though it faces competition from other hydride systems with superior storage capacity and kinetic performance; its significance lies mainly in fundamental studies of metal-hydrogen interactions and niche applications requiring specific electronic or catalytic properties.
