· Er10 Co4 Te4

Er₁₀Co₄Te₄ is a ternary intermetallic semiconductor compound combining erbium, cobalt, and tellurium elements. This material belongs to the rare-earth transition-metal telluride family and appears to be a research-phase compound rather than an established industrial material; it is likely being investigated for thermoelectric, optoelectronic, or magnetic applications given the combination of rare-earth and chalcogenide character. The incorporation of erbium (a lanthanide) into a cobalt-tellurium matrix suggests potential utility in specialized electronic or photonic devices where rare-earth luminescence or strong spin-orbit coupling could be leveraged.

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.
