· CoHfN3

CoHfN3 is an experimental interstitial nitride compound combining cobalt and hafnium, belonging to the family of refractory transition metal nitrides. This material is primarily of research interest for high-temperature structural applications, where the hafnium-cobalt nitride system is being investigated for potential use in extreme-temperature environments and as a candidate for next-generation refractory coatings or composites that demand enhanced hardness and thermal stability beyond conventional superalloys.
