HoB2Ir3
ceramic· JVASP-61762· HoB2Ir3
HoB2Ir3 is an intermetallic ceramic compound combining holmium boride with iridium, belonging to the rare-earth transition metal boride family. This is a research-phase material of significant interest for ultra-high-temperature applications due to the thermal stability of rare-earth borides combined with the mechanical robustness and oxidation resistance of iridium. While not yet widely deployed in production, materials in this class are being investigated for extreme environments where conventional superalloys and ceramics 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.
