Ta3Cr5N4
metal· JVASP-141111· Ta3Cr5N4
Ta3Cr5N4 is a transition metal nitride compound combining tantalum and chromium in a ceramic-like interstitial structure. This material belongs to the family of refractory metal nitrides, which are primarily of academic and emerging industrial interest for extreme-environment applications where conventional alloys fail. The tantalum-chromium nitride system is investigated for potential use in high-temperature coatings, cutting tools, and wear-resistant surfaces, where its hardness and thermal stability offer advantages over single-element nitride alternatives.

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.
