· JVASP-114177· CaSnS

Calcium tin sulfide (CaSnS) is a ternary ceramic compound combining alkaline-earth and group-14 elements with sulfur, belonging to the family of mixed-metal sulfide ceramics. This material is primarily of research interest for photovoltaic and optoelectronic applications, where its direct bandgap and sulfide composition offer potential advantages in thin-film solar cells and light-emitting devices as an alternative to more conventional chalcogenide semiconductors. CaSnS remains largely experimental; its appeal lies in earth-abundant constituent elements and the potential for lower toxicity compared to cadmium- or lead-based competitors in next-generation absorber layers and window materials.

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.
