What is zirconium-nitride (ZrN)? The zirconium-nitride, with its chemical formula ZrN, has excellent corrosion resistance. It also has high hardness, lubricity, and ductility. This coating is attractive due to its many properties. It is applied using physical vapor deposit. The coating can be in the form a yellow crystal powder or an attractive golden coating.

Zirconium nitride has a physical and chemical property of 7.09 and a microhardness between 9800-19600MPa. It also has a melting point of 2980 degrees plus or minus fifty. Zirconium is not soluble, although it is soluble to a small extent in inorganic acids. Zirconium (ZrN), because of its properties, can be used in various ways.

ZrN deposited by PVD is a light golden color, similar to that of elemental Gold. ZrN has a resistivity of 12.0mO*cm at room temperature, a temperature coefficient resistivity of 5.6*10-8O*cm/K and a superconducting threshold temperature of 10.4K. The relaxation lattice parameters is 0.4575nm. The elastic modulus and hardness are 450 GPa.
What is zirconium-nitride used for?
Zirconium Nitride is a hard ceramic similar to titanium nitride, and it’s a refractory like cement. This material can be used to make refractory materials as well as laboratory crucibles, cermets or cermet alloys. Physical vapor deposition is used as a coating method for medical equipment, industrial components (especially drills), automotive and aeronautical parts, and parts that are subject to high wear or corrosive conditions. In the case of alloying ZrN with Al, electronic structure is developed from the local bond symmetry octahedral. As the Al concentration increases, this symmetry is distorted and becomes more complex, with a higher degree of hardness.
For rockets, zirconium-nitride is recommended for the lining of hydrogen peroxide fuel tanks in airplanes and rockets.

Zirconium Nitride (ZrN) compounds are composed of different crystal structures. These vary depending on their composition. ZrN is an alloy compound that has been discovered in the ZrN system. Not only do they have excellent chemical characteristics, but they can also be used in junctions, diffusion laminations, low temperature instruments, etc. These compounds can be used in three-dimensional integrated electronic coils as well as metal-based semiconductor transistors. The ZrN compounds have superior wear resistance to pure zirconium, as well as oxidation, corrosion and wear resistance. In addition, they have a greater superconducting threshold temperature.

Preparation and use of zirconium powder
The main processes for the synthesis of zirconium oxide powder include direct nitridation using nitrogen on Zr metals, high-energy ball milling, microwave plasma, benzene method, aluminum nitridation and magnesium thermal reduction. A variety of routes are available for different particle sizes. The mass production of Zirconium Nitride and other Transition Metal Nitrides is possible. It should be noted, that due to the formation solid solution within the ZrNZrCZrO’ system, the nitriding product in CRN/CN is represented by Zr (N C O). It is necessary to perform a CRN two-step process. The nitrite is converted from zirconium carburide (ZrC), which was produced earlier as an intermediate. CN is a direct nitridation process of ZrO2 that only requires ONE heat treatment. It is possible that the latter method can be more time-efficient and energy-efficient in producing zirconium-nitride.

In oxygen reduction, zirconium nitride surpasses platinum
Pt-based materials play an important role in microelectronics, anti-cancer medicines, automotive catalysts, and electrochemical energy-conversion equipment. Pt, the most common catalyst for oxygen reduction reactions (ORR), is used in fuel cell and metal-air battery applications. Its scalable use, however, is limited due to its scarcity, high cost and toxicity. In this study, we demonstrate that zirconium nanoparticle nitride can replace or exceed Pt in ORR catalysts for alkaline environments. The synthesized ZrN (nanoparticles) exhibit high oxygen-reduction performance, and are as active as the commonly used commercial platinum/carbon catalyst (Pt/C). Both materials show the same half wave potential (E1/2 = 0.80 V), after 1000 ORR cycle, and ZrN shows a greater stability than Pt/C catalyst (DE1/2 than = 3 mV). In 0.1M KOH. ZrN is also more efficient and has higher cycles in zinc-air battery than Pt/C. ZrN replacing Pt may lower costs and encourage the use electrochemical energy devices. ZrN could also be useful in catalytic systems.
Enhanced Photoluminescence Combined with a Periodic array of Organic Dyes and Zirconium Nitride Nanoparticles
Due to their excellent optical properties, noble metals like gold have been used in plasma technology. The melting temperature of gold, particularly in nanoscale, is relatively low. These limitations in material are a barrier to the exploration of plasmons for multiple applications. Transition metal nitrides are promising materials substitutes because they exhibit acceptable plasma properties in the visible range and high mechanical and temperature stability. Zirconium (ZrN), a promising material substitute, has a carrier density higher than titanium (TiN), the gold Supplementary material most studied. In this research, we made a periodic ZrN-nanoparticle array and found out that the ZrN array increased the photoluminescence in the organic dyes. This photoluminescence was 9.7 times stronger when viewed under visible light. The experiments confirmed that ZrN is a good alternative to gold for further developing plasmons, and relieving the limitations associated to conventional materials.
