Zirconium nitride ({{chem2|auto=1|ZrN}}) is an inorganic compound used in a variety of ways due to its properties.
Properties
ZrN grown by physical vapor deposition (PVD) is a light gold color similar to elemental gold. ZrN has a room-temperature electrical resistivity of 12.0 μΩ·cm, a temperature coefficient of resistivity of 5.6·10−8 Ω·cm/K, a superconducting transition temperature of 10.4 K, and a relaxed lattice parameter of 0.4575 nm. The hardness of single-crystal ZrN is 22.7±1.7 GPa and elastic modulus is 450 GPa.{{Cite journal | doi = 10.1116/1.4825349| title = Physical properties of epitaxial ZrN/MgO(001) layers grown by reactive magnetron sputtering| journal = Journal of Vacuum Science & Technology A: Vacuum, Surfaces, and Films| volume = 31| issue = 6| pages = 061516| year = 2013| last1 = Mei | first1 = A.

Zirconium nitride is a hard ceramic material similar to titanium nitride and is a cement-like refractory material. Thus it is used in cermets and laboratory crucibles. When applied using the physical vapor deposition coating process it is commonly used for coating medical devices,{{cite journal|url = https://doi.org/10.1038/s41598-018-20013-z|title = Slate, A.J., Wickens, D.J., El Mohtadi, M. et al.
