· JVASP-49849· Nb3N5

Nb3N5 is a refractory metal nitride compound combining niobium with nitrogen, belonging to the family of transition metal nitrides known for high hardness and thermal stability. This material is primarily of research and development interest for applications requiring extreme hardness, thermal resistance, and chemical inertness, with potential use in cutting tools, wear-resistant coatings, and high-temperature structural applications where conventional carbides or nitrides reach their limits. Its notable advantage over traditional hard ceramics lies in its metal-like electrical and thermal conductivity paired with ceramic-level hardness, making it a candidate for advanced wear protection and specialized coating systems in demanding industrial environments.

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.
