· JVASP-66117· Ba4ReIr

Ba4ReIr is an intermetallic ceramic compound containing barium, rhenium, and iridium elements, representing a complex oxide or mixed-metal ceramic in the refractory materials family. This material is primarily of research and development interest rather than established in high-volume industrial production, with potential applications in extreme-temperature environments where the combination of refractory metals (Re, Ir) provides thermal stability and chemical resistance. Engineers would consider this material for specialized applications requiring high-temperature performance, corrosion resistance, or catalytic properties, though material availability, cost, and processing complexity typically limit adoption to advanced research programs and aerospace/nuclear contexts.

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.
