What is zirconium-nitride (ZnN)?
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. It is available in the form a yellow crystalline dust or an attractive golden coating.
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 plus or minus fifty. Zirconium is insoluble, only slightly soluble, in water. However, it can be dissolved in hydrofluoric and concentrated sulfuric acids. Zirconium (ZrN), because of its properties, can be used in a wide variety of applications.
ZrN produced by 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 ceramic hard material, similar to titanium nitride. It also acts as a refractory cement. This material can be used to make refractory materials as well as laboratory crucibles and cermets. 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. This symmetry is distorted by increasing the Al content. It becomes more complex, and harder.
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 a higher 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 and magnesium thermal reductions, carbothermal nitridation and direct carbon thermal zirconia nitriding. This route is suitable for a wide range of particle sizes and shapes. The mass production of Zirconium Nitride and other Transition Metal Nitrides is possible. It should be noted, that due to the formation solid solution in the ZrNZrCZrO’ system, the final nitriding product in CRN/CN is represented by this formula 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. The CN method is the direct nitridation ZrO2 with carbon and requires only one heat-treatment. It is possible that the latter method can be more time-saving 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 commonly used catalyst for oxygen reduction reactions (ORR), is found in fuel cell and metal-air battery applications. Its scalability is however limited by its scarcity as well as its cost and toxicity. 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 = 0.80V) after 1000 ORR cycle, but ZrN exhibits 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 the nanoscale case, is relatively low. These limitations in material are a barrier to the exploration of plasmons for multiple applications. 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 it 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.
