· CrNbN3

CrNbN3 is a ternary nitride ceramic compound combining chromium, niobium, and nitrogen—a research-phase material within the family of transition metal nitrides. This composition falls into the category of hard ceramic coatings and refractory materials, where multi-element nitride systems are being explored for enhanced hardness, thermal stability, and oxidation resistance beyond binary alternatives like CrN or NbN.

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.
