Zirconium nitride (ZrN) is an inorganic compound used in a variety of ways due to its 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.

When applied using the physical vapor deposition coating process it is commonly used for coating medical devices,[5] industrial parts (notably drill bits), automotive and aerospace components and other parts subject to high wear and corrosive environments.

Zirconium nitride was suggested as a hydrogen peroxide fuel tank liner for rockets and aircraft.
