HfNbN3
semiconductor· HfNbN3
HfNbN3 is a refractory ceramic compound combining hafnium, niobium, and nitrogen, belonging to the family of transition metal nitrides. This material is primarily of research and developmental interest for extreme-environment applications where thermal stability, hardness, and oxidation resistance are critical; it represents an emerging class of high-entropy and multi-component nitride ceramics being explored as alternatives to conventional refractory carbides and nitrides in cutting tools, coatings, and high-temperature structural applications.
