· JVASP-93811· Zr2TaN3

Zr₂TaN₃ is a refractory metal nitride compound combining zirconium and tantalum, belonging to the class of high-melting-point ceramic materials used in extreme-temperature and wear-resistant applications. This material is primarily of research and specialized industrial interest, valued for its thermal stability, hardness, and resistance to oxidation at elevated temperatures. It is explored in aerospace, tooling, and thermal management contexts where conventional alloys would fail, though it remains less commercialized than established alternatives like TiN or TaN coatings.

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.
