metal· JVASP-148162· Nb2N3
Nb₂N₃ is a ceramic niobium nitride compound that belongs to the family of refractory metal nitrides, which are known for exceptional hardness, thermal stability, and chemical resistance at elevated temperatures. While primarily a research and development material, niobium nitrides are investigated for demanding applications requiring wear resistance and thermal durability, particularly in cutting tools, coatings, and high-temperature structural components where conventional materials degrade. Engineers consider niobium nitrides as alternatives to carbides or traditional refractories when superior oxidation resistance or specific thermal properties are critical to design life.

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.
