CAS 7440-62-2 V powder price Vanadium Powder

Vanadium: element symbol V, silver gray metal, belongs to VB group in the periodic table, atomic number 23, Atomic weight 50.9414, body centered cubic crystal, common valence is +5, +4, +3, +2. Vanadium’s melting point is very high, and often with niobium, tantalum, tungsten, molybdenum as refractory metal. Malleable, It is hard and non-magnetic. It is resistant to hydrochloric and sulfuric acid, and is resistant to gas, salt, Water resistance is better than most stainless steels. Vanadium metal in dense state is more stable at room temperature. It does not interact with air, water or alkali and can resist dilute acids Vanadium is a silver-gray metal. The melting point is 1890±10℃, which is one of the rare metals with high melting point. It has a boiling point of 3380 ° C, pure vanadium is hard, non-magnetic, malleable, but if contained A small amount of impurities, especially nitrogen, oxygen, and hydrogen, can significantly reduce their plasticity.
