· JVASP-129225· HoIr3

HoIr3 is an intermetallic ceramic compound combining holmium and iridium in a 1:3 stoichiometric ratio, belonging to the rare-earth intermetallic family. This material is primarily explored in advanced research contexts for high-temperature applications due to the refractory nature of iridium and the potential for enhanced mechanical or thermal properties at extreme conditions. While not yet widely deployed in volume production, intermetallics of this type are investigated for aerospace propulsion systems, thermal barrier coatings, and high-temperature structural applications where conventional superalloys reach their limits.

Regulatory Screening

Environmental

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.
