· LaH2

Lanthanum dihydride (LaH₂) is an ionic ceramic compound belonging to the rare-earth metal hydride family, formed through the combination of lanthanum metal with hydrogen. This material is primarily investigated in research contexts for hydrogen storage applications, nuclear fuel cladding, and as a precursor compound in lanthanide chemistry, where its hydride structure offers potential advantages in systems requiring controlled hydrogen release or high-temperature stability. LaH₂ represents a materials class of significant interest in advanced energy and fuel applications, though industrial deployment remains limited compared to more conventional ceramics.
