· HoIr2

HoIr₂ is an intermetallic ceramic compound combining holmium and iridium, belonging to the rare-earth intermetallic family. This material is primarily of research and specialized high-temperature interest, investigated for potential applications in extreme environments where exceptional thermal stability and resistance to oxidation are critical. Its notable density and refractory characteristics position it as a candidate for advanced aerospace and nuclear applications, though industrial deployment remains limited compared to established ceramic alternatives.

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.
