· JVASP-90807· NaAsF6

Sodium hexafluoroarsenate (NaAsF₆) is an inorganic ceramic compound belonging to the hexafluorometallate family, characterized by strong As-F bonding within a crystalline ionic structure. This material is primarily used in specialized electrochemistry and fluorine chemistry applications, particularly as a supporting electrolyte in high-performance battery systems and electrochemical cells where its high ionic conductivity and chemical stability are advantageous. NaAsF₆ is notable for its role in lithium-ion and other advanced battery technologies where conventional electrolyte salts may be inadequate; however, it remains largely confined to research and specialized industrial settings due to arsenic content, regulatory constraints, and cost considerations relative to more common alternatives like LiPF₆.

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.
