· ScTaO2S

ScTaO2S is a mixed-metal oxysuIfide ceramic compound containing scandium, tantalum, oxygen, and sulfur. This is primarily a research-phase material being explored for photocatalytic and optoelectronic applications, as the combination of transition metals with anion mixing (oxide–sulfide) is designed to tailor band gaps and light absorption compared to conventional oxide or sulfide ceramics alone. Industrial adoption remains limited; potential drivers include photocatalytic water splitting, pollutant degradation under visible light, and solid-state device applications where tunable electronic properties are advantageous.

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.
