· Ho1 Au4

Ho1Au4 is an intermetallic compound combining holmium and gold in a 1:4 stoichiometric ratio, classified as a semiconductor material. This is a research-phase compound rather than a commercial alloy; intermetallic semiconductors in the rare-earth/noble-metal family are primarily investigated for specialized electronic and photonic applications where unique band structure properties are desired. Engineers would consider Ho1Au4 in advanced research contexts exploring rare-earth metallics for quantum devices, thermoelectric converters, or exotic semiconductor junctions where the combination of lanthanide and noble-metal chemistry offers properties unavailable in conventional semiconductors.

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.
