· JVASP-36381· RhN

Rhodium nitride (RhN) is a ceramic compound combining the refractory metal rhodium with nitrogen, forming a hard interstitial ceramic with potential for high-temperature and wear-resistant applications. This material remains largely in the research and development phase, explored for its hardness, thermal stability, and chemical inertness—properties typical of transition metal nitrides. RhN represents a candidate material for extreme environment applications where the exceptional properties of rhodium can be leveraged in ceramic form, though industrial adoption remains limited compared to established alternatives like tungsten carbide or titanium nitride.
