SUOYI Zirconium Nitride Powder Zrn Brown Powder Zirconium Nitride CAS 25658-42-8

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.

 

Zirconium nitride is a hard ceramic material similar to titanium nitride and is a cement-like refractory material. Thus it is used in refractories, cermets and laboratory crucibles. When applied using the physical vapor deposition coating process it is commonly used for coating medical devices,industrial parts (notably drill bits), automotive and aerospace components and other parts subject to high wear and corrosive environments. When alloyed with Al, the electronic structure develops from local octahedral bond symmetry of cubic ZrN that distorts for increasing Al content into more complex bonding and higher hardness. Zirconium nitride was suggested as a hydrogen peroxide fuel tank liner for rockets and aircraft.

 

Zirconium nitride (Zr-N) compounds have a variety of crystal structures with the change of composition. For example, in the Zr-N alloy system, the found alloy compounds are ZrN, o-Zr₃N₄, c-Zr₃N₄. They not only have excellent chemical properties, they can be used not only in Josephson junctions, diffusion laminates, low temperature meters, etc., but also in three-dimensional integrated electrical coils and metal-based transistors. At the same time, these Zr-N compounds are superior to pure zirconium in terms of wear resistance, oxidation resistance and corrosion resistance, and have a high superconducting critical temperature, so they may become very good superconductors and have high use value.
