· H1 Li1 F2

Lithium fluoride (LiF) is an inorganic ceramic compound notable for its high transparency across ultraviolet and infrared wavelengths, combined with ionic bonding that imparts significant rigidity and hardness. This material serves primarily in optical and photonic applications where broad-spectrum transparency is critical, as well as in specialized nuclear and thermal applications; it is valued over many glass alternatives for extreme ultraviolet (EUV) optics and radiation detection, though its hygroscopic nature and brittle character require careful handling and protective coatings in humid environments.

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.
