· JVASP-86691· Er3CoSi3

Er3CoSi3 is a rare-earth intermetallic compound combining erbium, cobalt, and silicon in a 3:1:3 stoichiometric ratio. This material belongs to the family of rare-earth transition metal silicides, which are primarily of research and development interest rather than established commercial use. Er3CoSi3 and related compounds in this family are investigated for potential applications in high-temperature structural materials, magnetism, and thermal management due to their crystalline intermetallic structure and rare-earth constituent properties.

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.
