LaH2
ceramic· 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.

Regulatory Screening
Environmental
RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
