Description of Vanadium Nitride powder
Vanadium nitride powder is typically produced through vanadium oxides (like V₂O₅) reduced in the presence of a carbon source and nitrogen gas to form vanadium nitride. Vanadium nitride’s combination of hardness, high-temperature stability, and catalytic properties makes it a versatile material for both industrial and academic research purposes.
Catalytic Applications: Researchers are focusing on the catalytic properties of VN for energy-related reactions, such as hydrogen evolution reactions (HER), ammonia decomposition, and nitrogen fixation. Its potential as a cheaper alternative to noble metals like platinum is a major research area
Energy Storage: Studies are exploring VN’s application in electrochemical energy storage, especially in supercapacitors and lithium-sulfur batteries. The emphasis is on improving cycling stability, energy density, and the overall performance of VN-based electrodes.
Material Properties Optimization: The focus is on enhancing the properties of VN powder through nanostructuring and doping with other elements. This research aims to improve VN’s hardness, wear resistance, and electrical conductivity for industrial applications.
Coating Development: Academic research is delving into the development of VN-based coatings for improving surface hardness, corrosion resistance, and wear resistance of tools and components, particularly in extreme environments.
Sustainability in Steel making: VN is being studied for its ability to reduce the amount of vanadium required in steel production, promoting more cost-effective and environmentally friendly methods for manufacturing high-strength steels.

- Advanced ceramics: VN can be used in ceramic composites, improving the strength and high-temperature stability of ceramic materials.
Reference
- High purity vanadium nitride (VN) powders were prepared via a two-step process using vanadium trioxide (V2O3) as the raw material. The V2O3 was firstly reduced at 873 K in Ar atmosphere via magnesiothermic reduction reaction to get the mixture of V and MgO, and then the products were further nitrided at 1473 K in N2 atmosphere. Finally, the as-prepared samples were acid-leached to obtain pure VN powders.
