· JVASP-102296· YHoIr2

YHoIr2 is an intermetallic ceramic compound combining yttrium, holmium, and iridium elements, representing a specialized high-density material in the refractory intermetallic family. This is a research-phase compound rather than an established commercial material; intermetallics of this composition are investigated for extreme-temperature structural applications where conventional alloys fail, particularly in aerospace and nuclear contexts where thermal stability and chemical resistance are critical. The material's high density and rare-earth constituents suggest potential use in high-performance applications requiring resistance to oxidation, thermal cycling, or aggressive chemical environments, though industrial adoption remains limited pending demonstration of manufacturing scalability and cost-effectiveness.

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.
