· S1 O4 F1 Na3

Sodium fluoride silicate (Na₃SO₄F), commonly known as cryolite or a cryolite-related compound, is an inorganic ceramic salt belonging to the fluoride mineral family. This material is primarily valued in metallurgical and chemical processing industries, where it serves as a flux in aluminum smelting and as a raw material for specialty glass and enamel coatings. Engineers select this compound for high-temperature applications requiring chemical stability and its ability to lower melting points of other oxides, making it essential in reducing production costs and energy consumption in primary aluminum extraction.

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.
