YbCu2S2
metal· JVASP-92308· YbCu2S2
YbCu₂S₂ is an intermetallic compound combining ytterbium, copper, and sulfur, belonging to the family of rare-earth metal chalcogenides. This is primarily a research material studied for its electronic and thermal transport properties rather than a production engineering material; it represents the broader class of rare-earth-transition metal sulfides of interest for thermoelectric and semiconducting applications where tunable band structure is advantageous.

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.
