Cu2As3
metal· JVASP-108816· Cu2As3
Cu₂As₃ is an intermetallic compound combining copper and arsenic, belonging to the family of binary metal arsenides with potential applications in semiconductor and advanced materials research. While not widely used in mainstream engineering, this compound is of interest in specialized fields including thermoelectric materials development and semiconductor device research, where its electrical and thermal transport properties are being evaluated. Engineers would consider this material primarily in experimental or niche applications rather than conventional industrial production, given the toxicity concerns associated with arsenic and the material's limited commercial availability.
