This mixture of halide anions—fluoride, chloride, and bromide—finds application in specialized analytical and industrial processes where selective reactivity or ionic conductivity is required. The combination can be used in molten salt systems for metal extraction or purification, leveraging the differing redox potentials and complexation behaviors of the halides. In some cases, such mixtures serve as fluxing agents in high-temperature reactions, aiding in the dissolution of refractory materials. They may also be employed in electrochemical applications, such as in certain types of batteries or sensors, where a tailored ionic environment enhances performance. Additionally, this anion blend can assist in the synthesis of mixed-halide compounds, particularly in the preparation of perovskite materials for optoelectronic devices, where halide composition influences bandgap and stability.
