· JVASP-116263· LiH2

Lithium hydride (LiH₂) is an ionic ceramic compound in the metal hydride family, characterized by very low density and significant hydrogen content by mass. Though primarily of research and specialized industrial interest rather than a mainstream engineering material, LiH₂ is investigated for hydrogen storage, neutron shielding in nuclear applications, and as a potential solid-state energy carrier in advanced energy systems. Its extreme lightness and high theoretical hydrogen density make it notable for aerospace and defense contexts where weight and radiation protection are critical, though synthesis, stability, and handling challenges limit current widespread adoption.

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.
