English name: Vanadium Pentoxide (Flake) Molecular formula: V2O5 CAS NO.:1314-62-1 Density:3.357g/cm3 Melting point:690 Boiling point:1750 Aqueous solubility:1g/125mL Appearance : gray black flake Application: Vanadium flakes are mainly used in the iron and steel industry. By refining the structure and grains of steel, the grain coarsening temperature is increased, thereby increasing the strength, toughness and wear resistance of the steel. In addition, vanadium flakes are excellent in titanium alloy Improved effect, used as an additive in the aerospace field.
