ErCuS2
metal· JVASP-57536· ErCuS2
ErCuS2 is a ternary intermetallic compound combining erbium (a rare-earth element), copper, and sulfur. This is a specialized research material rather than a production commodity; it belongs to the family of rare-earth chalcogenides and represents compounds of scientific interest for their unique electronic and thermal properties at the intersection of metallurgy and solid-state chemistry. ErCuS2 has been studied in academic contexts for potential applications in semiconducting, thermoelectric, or photonic devices where rare-earth components can provide tunable band structure and unusual electromagnetic behavior, though it remains primarily a laboratory compound without established high-volume industrial adoption.

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.
