· KTaO2S

KTaO₂S is a mixed-anion semiconductor compound combining potassium, tantalum, oxygen, and sulfur in an anionic framework structure. This is a research-stage material being investigated for photocatalytic and optoelectronic applications, as the substitution of oxygen with sulfur can modulate the bandgap and enhance light-absorption properties compared to oxide-only tantalates. The material represents an emerging class of oxysulifdes with potential relevance to solar energy conversion, environmental remediation, and next-generation semiconductor device development.

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.
