Property: Vanadium has a high melting point and is often referred to as a refractory metal along with niobium, tantalum, tungsten, and molybdenum. Has extensibility, hard texture, and is non-magnetic. Has the ability to resist hydrochloric acid and sulfuric acid, and performs better than most stainless steels in terms of gas resistance, salt resistance, and corrosion resistance. Vanadium, a dense metal at room temperature, is relatively stable and does not interact with air, water, or alkali. 

Purpose: 

1) Adding microalloying element vanadium to steel has the effect of refining grain size and improving the strength and toughness of materials. The precipitation strengthening effect of microalloying elements replaces the strengthening effect of carbon, and can also improve the welding performance of materials. 

2) It has excellent comprehensive properties such as low density, high specific strength, good corrosion resistance, and good processability. It can also serve for a long time above 400 ℃ and maintain high strength. Can be used to manufacture fans, blades, press plates, and pressure components for aircraft engines. 

3) The capture area for fast neutrons is small, it is resistant to corrosion by liquid metal sodium, and has good high-temperature creep strength. This property can extend the load and life of nuclear reactor walls, and can achieve higher reaction temperatures compared to carbon steel walls. 

4) Vanadium based solid solutions have many advantages as hydrogen storage materials, such as large hydrogen storage capacity, high hydrogen storage density, fast hydrogen absorption and desorption speed, and safe storage and transportation. 

5) Vanadium batteries have obvious advantages such as high power, large capacity, high efficiency, long lifespan, fast response speed, instant charging, high safety, and low cost. They are considered as the preferred choice for energy storage equipment supporting solar and wind power generation devices, electric vehicle power supply, emergency power supply systems, power station energy storage peak shaving, renewable energy grid connected power generation, urban power grid energy storage, remote power supply, UPS systems, and other fields. 

6) VC has a high solubility in the Co phase of metal ceramics and a low eutectic temperature with Co, which inhibits the growth of WC grains even at higher temperatures (1300 ℃~1350 ℃). In theory, VC is the best grain growth inhibitor and more economical than other metal carbides. In addition, VC can also lower the Curie point of WC Co based metal ceramics, resulting in non-magnetic properties. 

7-doped yttrium neodymium vanadate crystal is an important laser matrix crystal, mainly used in optical isolators, polarizing devices, and circulators. VO2 thin film materials have wide applications in optoelectronic switches, optical holography, electronic scanning lasers, temperature sensitive semiconductor devices, and optical storage. 

Storage method: This product should be sealed and stored in a dry and cool environment. It should not be exposed to air for a long time to prevent moisture from causing aggregation, affecting dispersion performance and usage effect. In addition, it should be avoided from heavy pressure and not in contact with oxidants. It should be transported as ordinary goods.
