Barium fluoride

Barium fluoride (BaF2, CAS 7787-32-8, EC 232-108-0) is an inorganic fluoride salt of barium, also referenced commercially as barium difluoride or BaF2. It carries no E-code designation and is categorised within the salts and minerals group. It is distinct from barium sulfate and other barium compounds in its fluoride-specific reactivity.

In metallurgical and electronics applications, BaF2 functions as a flux agent that lowers melting points in metal processing and improves conductivity in certain ceramic formulations. In plastics and polymer systems, it acts as a flame retardant by releasing fluorine species that interrupt combustion chains, and as a catalyst or buffer in controlled pH environments requiring stable fluoride ion activity.

This product is supplied as a white fine powder meeting industrial-grade specifications and is registered under REACH. Procurement teams should verify supplier SDS documentation for classification under CLP Regulation, given barium compound toxicity thresholds. HS code 28261990 applies for EU import and export declarations.
