· JVASP-86798· HoSi2Au2

HoSi2Au2 is an intermetallic compound combining holmium, silicon, and gold, representing a ternary metallic system with potential high-temperature applications. This is primarily a research-phase material studied for its thermal and electronic properties rather than an established commercial alloy; compounds in the rare-earth silicide–gold family are investigated for specialized high-temperature structural applications, thermoelectric devices, and electronic contact materials where the combination of refractory silicide behavior and noble metal properties offers potential advantages over conventional single-phase alloys.

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.
