· JVASP-132079· LuF

Lutetium fluoride (LuF₃) is an inorganic ceramic compound belonging to the rare-earth fluoride family, characterized by high density and ionic crystal structure. It is used primarily in optical applications, nuclear engineering, and specialized high-temperature environments where chemical inertness and radiation resistance are required. LuF₃ is notably valued for its transparency in the infrared spectrum and resistance to thermal shock, making it an alternative to other rare-earth fluorides in niche defense, space, and nuclear fuel applications.

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.
