Vanadium Molecular formula: V Appearance: silvery grey metallic. Classification: Metallic Purity: 99.5%~99.9% Impurities:(%) Fe ≤0.032 Si ≤0.004 Al ≤0.01 Cr ≤0.005 O ≤0.10 H ≤0.02 Packing in 25kg, 50kg or 100kg iron drums. vanadium is available in several forms including foil, granules, powder, rod, and turnings. Use, Approximately 80% of vanadium produced is used as ferrovanadium or as a steel additive. Nature: Vanadium is a soft and ductile, silver-grey metal. It has good resistance to corrosion by alkalis, sulfuric and hydrochloric acid.
