· TaNbN3

TaNbN₃ is a refractory metal nitride compound combining tantalum, niobium, and nitrogen, belonging to the family of high-performance ceramic coatings and hard materials. This material is primarily of research and development interest for extreme-environment applications where conventional hard coatings fail, including cutting tools, wear-resistant coatings, and thermal barrier systems in aerospace and industrial manufacturing. Its appeal lies in the exceptional hardness and thermal stability of the tantalum-niobium nitride system, offering potential advantages over single-element nitride coatings (such as TiN or CrN) in terms of oxidation resistance and mechanical performance at elevated temperatures.

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.
