KNaS2O7
ceramic· JVASP-96795· KNaS2O7
Potassium sodium disulfate (KNaS2O7) is an inorganic salt ceramic compound containing sulfate groups, typically encountered as a crystalline solid in industrial chemistry applications. This material appears primarily in chemical processing, metallurgical operations, and laboratory settings where mixed alkali sulfates serve functional roles in flux systems, thermal treatment processes, or analytical chemistry. KNaS2O7 is notable for its thermal stability and hygroscopic properties, making it relevant in high-temperature metallurgical contexts where it can act as a flux or processing aid, though it is less commonly specified as a primary structural or functional ceramic compared to traditional oxide ceramics.

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.
