· JVASP-118886· LiF2

LiF2 (lithium fluoride) is an ionic ceramic compound belonging to the fluoride ceramic family, characterized by strong ionic bonding and high chemical stability. It is primarily investigated in research and specialized applications requiring excellent transparency in the ultraviolet and infrared spectral regions, along with superior thermal and chemical resistance. The material is valued in optics, nuclear applications, and high-temperature environments where conventional glasses and ceramics would degrade, though it remains less common in mainstream engineering compared to established alternatives like fused silica or sapphire.

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.
