· CaTaO2S

CaTaO₂S is an oxynitride ceramic compound combining calcium, tantalum, oxygen, and sulfur—a member of the mixed-anion ceramic family that blends oxide and chalcogenide chemistry. This is primarily a research material under investigation for photocatalytic and optoelectronic applications, particularly for visible-light-driven catalysis and energy conversion, where the sulfur substitution modifies the bandgap compared to purely oxide alternatives like CaTaO₃. Engineers would consider this material when designing next-generation photocatalytic systems for water treatment or solar-driven chemical synthesis, as the oxygen-sulfur composition offers tunable electronic properties not accessible in conventional oxide ceramics.

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.
