Description
Lithium fluoride (CAS 7789-24-4, EC 232-152-0, formula FLi) is an inorganic salt supplied under trade designations including TLD 100, NTL 50, PTL 710, and NSC 12957. It carries no assigned E-code. The compound is categorised within the Salts & Minerals group and is referenced in thermoluminescence dosimetry literature as LFDNB.
In electronics manufacturing, lithium fluoride acts as a flux and dopant, lowering melting points in ceramic and glass matrices to improve processability. In plastics and polymer compounding, it functions as a flame retardant by releasing fluorine species that interrupt combustion chain reactions. It also serves as a pH buffer and antimicrobial agent in textile processing baths.
Lithium fluoride is available in technical and high-purity grades compliant with REACH registration requirements. Standard packaging includes multi-wall bags and fibre drums sized for industrial procurement volumes. Buyers should confirm grade suitability against Ph.Eur. or internal specification sheets prior to ordering.
