· JVASP-108860· Na3AsF6

Sodium arsenic fluoride (Na₃AsF₆) is an inorganic ceramic compound belonging to the fluoride salt family, characterized by ionic bonding between sodium cations and arsenic fluoride complex anions. This material is primarily encountered in specialized industrial applications including metal surface treatment, particularly as a flux or processing agent in aluminum and magnesium metallurgy, and in laboratory/research settings as a reagent for fluorination chemistry. Na₃AsF₆ is notable for its strong fluoride-releasing capability, making it valuable in applications requiring aggressive fluoride activity, though its use is limited by arsenic content and associated toxicity concerns compared to safer fluoride alternatives.
