· JVASP-91411· Ba2SnS4

Ba2SnS4 is a barium tin sulfide ceramic compound belonging to the chalcogenide family, characterized by mixed-metal sulfide bonding. This material is primarily investigated in research settings for optoelectronic and photovoltaic applications, where its semiconducting properties and wide bandgap make it a candidate for solar absorbers, photodetectors, and light-emitting devices; it represents an emerging alternative to traditional II-VI semiconductors with potential advantages in thermal stability and earth-abundant constituent elements compared to cadmium or lead-based systems.

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.
