Zirconium nitride ( Zr N ) 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. ^[4]

Uses

Zirconium nitride coated cutters.

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, ^[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. ^[6]
