· AuInO2S

AuInO₂S is a mixed-metal ceramic compound combining gold, indium, oxygen, and sulfur—a quaternary oxide-sulfide that represents an emerging class of multifunctional ceramics. This material is primarily of research interest for optoelectronic and photocatalytic applications, where the combination of noble and transition metals can enable tunable band gaps and enhanced light absorption. Its potential advantages include improved photocatalytic efficiency, semiconductor properties suitable for thin-film devices, and possible photovoltaic performance compared to simpler binary or ternary oxides.

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.
