· JVASP-14923· KSnS2

KSnS₂ is an inorganic ceramic compound composed of potassium, tin, and sulfur, belonging to the thiostannate family of materials. This material is primarily of research and developmental interest rather than established industrial production; it is investigated for applications requiring mixed-valent metal sulfides with potential semiconducting or ion-conducting properties. The potassium-tin-sulfur system offers promise in solid-state energy storage, photovoltaic research, and specialty catalysis where sulfide ceramics provide chemical stability and tunable electronic characteristics.

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.
