Li3H
ceramic· JVASP-116286· Li3H
Lithium hydride (Li₃H) is an ionic ceramic compound combining lithium metal with hydrogen, representing a materials chemistry boundary between metallic and ceramic behavior. This compound exists primarily in research and specialized aerospace contexts rather than widespread commercial use, valued for its extremely low density and potential as a solid-state hydrogen storage or neutron shielding medium in advanced nuclear applications.

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.
