· JVASP-92656· HoSi3Ir

HoSi3Ir is an intermetallic ceramic compound combining holmium, silicon, and iridium, belonging to the rare-earth silicide family. This material is primarily of research and development interest for high-temperature structural applications where exceptional hardness and chemical stability are required. Its combination of a rare-earth element with noble metal (iridium) and refractory ceramic (silicon) suggests potential use in extreme environments, though commercial deployment remains limited and applications are typically exploratory or specialized.

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.
