V Metal Vanadium
Vanadium: element symbol V, silver gray metal, in the periodic table belongs to VB group, atomic number 23, atomic weight 50.9414, BCC crystal, common valence is + 5, + 4, + 3, + 2. Vanadium has a high melting point and is often called refractory metal together with niobium, tantalum, tungsten and molybdenum. It is malleable, hard and non-magnetic. It has the ability to resist hydrochloric acid and sulfuric acid, and is better than most stainless steel in gas, salt and water corrosion resistance. At room temperature, the dense state of vanadium is relatively stable. It does not react with air, water and alkali, and is resistant to dilute acid.
Vanadium is a silver gray metal. The melting point is 1890 ± 10 ℃, which is one of the rare metals with high melting point. Its boiling point is 3380 ℃, pure vanadium is hard, non-magnetic and ductile, but if it contains a small amount of impurities, especially nitrogen, oxygen, hydrogen, etc., it can significantly reduce its plasticity.
