· JVASP-119571· FeSO4F

FeSO₄F is an iron fluorosulfate ceramic compound combining iron(II) sulfate with fluoride components, representing an emerging functional ceramic in the iron-based oxide/salt family. This material is primarily under investigation in research contexts for energy storage and electrochemical applications, particularly as a cathode or electrolyte component in advanced battery systems where iron-based chemistries offer cost and abundance advantages over transition metal alternatives. Its fluoride-containing structure may provide enhanced ionic conductivity and electrochemical stability compared to conventional iron sulfates, making it of interest for developers pursuing scalable, earth-abundant battery chemistries.

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.
