· BaTiO2S

BaTiO₂S is a mixed-anion semiconductor compound combining barium, titanium, oxygen, and sulfur, belonging to the family of oxychalcogenides or sulfide-oxide perovskites. This material is primarily of research interest for photocatalytic and optoelectronic applications, where the incorporation of sulfur into a titanium oxide framework is expected to narrow the bandgap and enhance visible-light absorption compared to conventional titanium dioxide (TiO₂). While not yet widely established in mainstream industrial production, BaTiO₂S represents a promising avenue in the development of next-generation semiconductors for environmental remediation and energy conversion, particularly in applications where improved light harvesting under visible spectrum conditions is critical.

Export Control

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.
