· La2 F6

La₂F₆ (lanthanum fluoride) is an inorganic ceramic compound belonging to the rare-earth fluoride family, characterized by ionic bonding between lanthanum cations and fluoride anions. This material is primarily of research and specialized industrial interest, used in optical applications (particularly infrared optics and laser systems), as a precursor for rare-earth element processing, and in advanced ceramic coatings where chemical stability and thermal properties are critical. Lanthanum fluoride offers advantages over some alternatives due to its high refractive index in the infrared spectrum, chemical inertness, and resistance to hydrolysis compared to many other rare-earth compounds.

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.
