· Nb1 N1

Niobium nitride (NbN) is a ceramic compound semiconductor belonging to the refractory metal nitride family, known for its high hardness, chemical stability, and metallic conductivity. It is primarily used in hard coatings for cutting tools, wear-resistant applications, and thin-film electronic devices, where its combination of hardness and electrical conductivity offers advantages over traditional ceramics. The material is also of interest in superconductor research and as a barrier/adhesion layer in microelectronic manufacturing due to its thermodynamic stability with both metals and semiconductors.

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.
