· JVASP-155416· KTaAg2S4

KTaAg2S4 is a ternary metal sulfide compound combining potassium, tantalum, and silver in a crystalline structure. This is primarily a research material studied for its electronic and photocatalytic properties rather than a conventional engineering alloy; compounds in this family are investigated for potential applications in semiconductors, photocatalysis, and solid-state chemistry where mixed-metal sulfides can exhibit unique band gaps and light-responsive behavior.

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.
