What is zirconium-nitride (ZnN)?
The zirconium-nitride, with its chemical formula ZrN, has excellent corrosion resistance. It also has good lubricity, ductility, and high hardness. This coating is attractive due to its many properties. It is applied using physical vapor deposit. It is available in a yellow crystalline coating or attractive golden coating.
The zirconium-nitride has a physical and chemical property of 7.09 and a microhardness between 9800 and 19600MPa. It also has a melting point of 2980 degrees Celsius plus or minus fifty. Zirconium is insoluble, but slightly soluble, in water. It’s soluble, however, in hydrofluoric and concentrated sulfuric acids. Zirconium (ZrN), because of its properties, can be used in many different ways.
ZrN grown through physical vapor deposit (PVD), is similar in color to 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 a cement like refractory. This material can be used to make refractory materials as well as laboratory crucibles, cermets or cermet alloys. Physical vapor deposition is a coating method that is commonly used on medical equipment, industrial components (especially drill bits), aerospace and automotive parts, as well as other parts exposed to corrosive and high-wear environments. In the case of alloying ZrN with Al, electronic structure is developed from the cubic ZrN’s local octahedral symmetry. As the Al concentration increases, the symmetry is distorted and becomes more complex, with a higher hardness.
For rockets, zirconium-nitride is a good choice 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 reduction, magnesium thermal, carbothermal nitridation. All sizes and particle shapes can be processed using the appropriate routes. 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. In contrast, the CN method is the direct nitridation ZrO2 when carbon is present. Only one heat treatment procedure is needed. It is possible that the latter method can be more time- 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 toxicity, scarcity, and cost limit its potential use. In this study, we demonstrate that nano-particles of zirconium (ZrN), 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 0.1 M 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 low. These limitations in material are a barrier to the exploration of the application of plasmons across multiple fields. Transition metal nitrides are promising substitutes for conventional materials because of their high mechanical and thermo-mechanical stability, and also acceptable plasma properties in the visible range. 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.
