· JVASP-75785· TaAsIr2

TaAsIr2 is an intermetallic ceramic compound combining tantalum, arsenic, and iridium in a defined stoichiometric ratio. This material represents an exploratory composition in the refractory intermetallic family, with potential applications in extreme-environment engineering where high-temperature stability, chemical inertness, and density are critical. Research-stage compounds of this type are typically investigated for specialized aerospace, high-temperature catalysis, or nuclear applications where conventional superalloys or ceramics reach performance limits.

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.
