· JVASP-16390· ErCuAs2

ErCuAs2 is an intermetallic compound combining erbium (a rare-earth element) with copper and arsenic, forming a metallic phase typically encountered in research settings rather than established industrial production. This material belongs to the family of rare-earth intermetallics, which are studied for potential applications in thermoelectric devices, magnetic materials, and high-performance electronic components where the rare-earth element's electronic properties can be exploited. While not a commodity material, compounds in this chemical family are of interest to researchers investigating advanced energy conversion and materials with tailored electronic or magnetic behavior.

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.
