· JVASP-115178· LiB2

LiB2 is a lithium boride ceramic compound belonging to the refractory ceramic family, characterized by its lightweight structure and rigid lattice bonding. While primarily recognized in research and advanced materials development contexts, lithium borides are investigated for applications requiring materials that combine low density with mechanical stiffness at elevated temperatures. This material class is of particular interest in aerospace, defense, and neutron shielding applications where weight reduction and thermal stability are critical design drivers.

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.
