Ba(CuS)2
metal· Ba(CuS)2
Ba(CuS)₂ is a barium copper sulfide compound—an inorganic metal sulfide that belongs to the family of mixed-metal chalcogenides. This is primarily a research and development material rather than a commodity engineering material, investigated for semiconductor and photovoltaic applications due to its tunable electronic properties and potential for light absorption in thin-film devices.

Export Control
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.
