· JVASP-92703· DySi3Ir

DySi3Ir is an intermetallic ceramic compound combining dysprosium, silicon, and iridium—a rare-earth transition metal silicide belonging to the family of refractory intermetallics. This material is primarily of research and development interest rather than established high-volume production, investigated for extreme-temperature structural applications where conventional ceramics or superalloys reach their limits. The combination of a heavy rare-earth element (dysprosium) with iridium—one of the most refractory metals—suggests potential for thermal stability and oxidation resistance in aerospace, power generation, or specialized industrial heating environments where ultra-high temperature performance and chemical stability are critical.

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.
