Ta1 Ir3

semiconductor

· Ta1 Ir3

Ta1Ir3 is an intermetallic compound combining tantalum and iridium in a 1:3 atomic ratio, belonging to the refractory metal alloy family. This material is primarily of research and development interest rather than established industrial production, with potential applications in extreme-temperature environments where the high melting points and chemical stability of both constituent metals offer advantages. The iridium-rich composition suggests investigation for specialized aerospace, catalytic, or high-performance electronic applications where corrosion resistance and thermal stability are critical.

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.
