· JVASP-56824· HoSi2Ir2

HoSi₂Ir₂ is an intermetallic ceramic compound combining holmium, silicon, and iridium—a rare-earth transition metal system typically investigated for high-temperature structural applications. This material belongs to the family of refractory intermetallics and is primarily a research-phase compound rather than a commodity product; it is studied for environments where thermal stability, oxidation resistance, and mechanical rigidity at elevated temperatures are critical, such as aerospace propulsion systems and extreme-service electronics.

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.
