The role and use of vanadium
The nature of vanadium: Physical properties: Vanadium is a silver-gray metal. The melting point is 1919 plus or minus 2 degrees Celsius, which belongs to the category of high-melting-point rare metals. Its boiling point is 3000-3400 degrees Celsius, and the density of vanadium is 6.11 grams per cubic centimeter.
Chemical properties: Pure vanadium is malleable, but if it contains a small amount of impurities, especially nitrogen, oxygen, hydrogen, etc., it can also significantly reduce its plasticity.
General source: mainly mineral green sulfur vanadium stone vs4 vanadium aluminum ore vanadium uranium ore. Vanadium can combine with oxygen in divalent, trivalent, tetravalent, and pentavalent forms to form four oxides, vanadium monoxide (VO), vanadium trioxide (V2O3), vanadium dioxide, vanadium pentoxide.
The use of vanadium and its compounds Vanadium is used in steel because vanadium can form stable carbon compounds (V4C3) with carbon in steel. It can refine the structure and grain of steel and increase the grain roughness temperature. Significantly improve the performance of steel. It can increase the strength, toughness, corrosion resistance, wear resistance and impact load bearing capacity of steel.
