· Zr1 Co1 As1

ZrCoAs is an intermetallic compound belonging to the half-Heusler family of semiconductors, characterized by a 1:1:1 stoichiometric ratio of zirconium, cobalt, and arsenic. This material is primarily of research and development interest for thermoelectric applications, where its electronic and thermal transport properties are being investigated for solid-state heat-to-electricity conversion. ZrCoAs and related half-Heusler compounds are attractive alternatives to traditional thermoelectric materials due to their tunable band structure, potential for high thermopower, and compatibility with high-temperature operating environments, though industrial adoption remains limited compared to established thermoelectric materials.

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.
