La7Ir3
ceramic· JVASP-154780· La7Ir3
La7Ir3 is an intermetallic ceramic compound combining lanthanum and iridium, belonging to the rare-earth intermetallic family. This material is primarily of research interest rather than established commercial use, being investigated for high-temperature structural applications where the combination of a refractory metal (iridium) and rare-earth element offers potential for enhanced oxidation resistance and thermal stability. Engineers would consider this material in contexts where conventional superalloys reach their limits, though its practical engineering adoption remains limited pending further development of processing and cost optimization.

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.
