ceramic

· Y(SiIr)2

Y(SiIr)₂ is a ternary intermetallic ceramic compound combining yttrium, silicon, and iridium in a Heusler or related crystal structure. This is a research-stage material rather than an established commercial ceramic, belonging to the family of refractory intermetallics that offer potential for high-temperature structural applications. The combination of a heavy transition metal (iridium) with a rare-earth element (yttrium) and silicon suggests interest in exploring enhanced hardness, oxidation resistance, and thermal stability for extreme-environment engineering.

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.
