· JVASP-121478· ZrB4Ir3

ZrB₄Ir₃ is an intermetallic compound combining zirconium boride and iridium, representing a research-phase material in the ultra-high-temperature metals family. While not yet widely commercialized, this compound belongs to the emerging class of boride-based intermetallics investigated for extreme-environment applications where conventional superalloys reach their thermal limits. The material's notable stiffness and density suggest potential for aerospace and defense systems operating at temperatures and stress levels beyond current material capabilities.

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.
