Product application: 
Vanadium carbide, as a grain growth inhibitor, has been widely used in the preparation of ultrafine hard alloys. Its mechanism of action is that grain growth mainly occurs during the dissolution and precipitation process of WC. WC dissolves in the liquid phase and precipitates on larger WC crystals. The inhibitor changes the interfacial free energy of WC Co, thereby restricting the dissolution precipitation process, reducing the dissolution precipitation rate, and slowing down the process of grain growth. According to data reports, adding VC can increase the lifespan of hard alloys by 20%, but its mechanism of action is still unclear. Due to the high activity and fast atomic migration rate of ultrafine VC, it is more conducive to particle diffusion and easier to dissolve in cobalt phase, thus effectively preventing the dissolution precipitation of tungsten carbide. Therefore, the development of ultrafine VC for ultrafine hard alloys is of great significance. Vanadium carbide has the general characteristics of transition metal carbides such as high hardness, melting point, and high temperature strength, as well as good electrical and thermal conductivity, making it widely used in fields such as steel metallurgy, hard alloys, electronic products, catalysts, and high-temperature coating materials. Among them, the addition of vanadium carbide to steel can improve its comprehensive properties such as wear resistance, corrosion resistance, toughness, strength, ductility, hardness, and thermal fatigue resistance, and make the steel have strong weldability. It can also eliminate inclusions and be used as a wear-resistant material in different cutting and wear-resistant tools. 
2. Vanadium carbide is used in WC Ni hard alloys, and adding a small amount of vanadium carbide can effectively reduce the Curie point of the alloy, causing it to change from ferromagnetism to paramagnetism at room temperature. Adding VC can reduce the saturation magnetization, remanence, coercivity, magnetic energy product, permeability, and Curie temperature of WC-10% Ni hard alloy, producing non-magnetic alloys. Its mechanism of action is that the solid solution of VC in the bonding phase increases the atomic spacing a of the Ni lattice, thereby increasing the ratio of a to the radius r of the unfilled electron layer of Ni, and transforming the alloy from magnetic to non-magnetic. 
3. Solid solution formed by vanadium carbide and other metal carbides, used as a matrix or additive in the production of tungsten free hard alloys. If vanadium carbide is added in moderation, the wear resistance, high-temperature strength, and high-temperature oxidation resistance of TiB2 Fe Mo hard alloy can be improved. 
Vanadium carbide can be used as an effective catalyst due to its high activity, selectivity, stability, and ability to resist catalyst poisoning in hydrocarbon reactions. As a new type of catalyst, it has been widely applied. Such as the synthesis of NH3. 
The main reason why high vanadium high-speed steel has excellent wear resistance and safety is by increasing the content of vanadium element, thereby forming high hardness vanadium carbides. High vanadium high-speed steel, a new type of steel used in the development of new wear-resistant materials, has a lifespan three times that of high chromium cast iron and ten times that of high manganese steel. 
6. Vanadium carbides have good morphology (minimal fragmentation of the matrix) and high hardness (the microhardness of vanadium carbide can reach HV2600), which can make high vanadium iron carbon alloys exhibit excellent wear resistance. 
A new method has recently been developed abroad to metallurgically bond a thin layer of vanadium carbide onto the surface of a tool, which can improve the efficiency of machining parts by several times, even dozens of times. This method involves placing tool steel cutting tools in a borate bath containing carbide elements, which allows vanadium to thermally diffuse into the matrix of the tool steel and combine with carbon. The commonly used matrix materials are Cr5MoLV and Cr12MoV alloy tool steels. The hardness of this coating is as high as 3200-3800HV, and it is not easy to peel off. 20% of the coating thickness (0.014-0.0125mm) penetrates into the tool surface, thus greatly improving the tool life. 
8. It can be used as a raw material for extracting pure vanadium metal.
