Vanadium

History

Vanadium was discovered in 1830 by  Niels Sefstremom. He named it in honor of the Scandinavian goddess of beauty Vanadis. Metal with a purity of 96% was obtained in 1869 the English scholar H. Roscoe. After opening analina Russian scientist NN Zinin in 1842, vanadium oxide is widely used in the coloring industry. During the First World War, vanadium was used as a catalyst in the reaction to sulfuric acid. In 1905, G. Ford, began to investigate the alloying steel with vanadium. This allowed him to significantly alleviate the weight and price of the car.
 
Nowadays
 
Vanadium is still used for alloying steel. This gives to steel strength, lightness, resistance to high temperatures, flexibility. Adding 3% vanadium to aluminum makes the metal very hard. This alloy is called «Vaviliom». Alloy for musical instruments made of aluminum and 2% vanadium. The alloy of nickel and 18-20% of vanadium used in the manufacture of chemical glassware. Adding vanadium in gold attached to the metal hardness, is not inherent in normal conditions.
