Nils Gabriel Sefström (2 June 1787 – 30 November 1845) was a Swedish chemist.Sefström was a student of Berzelius and, when studying the brittleness of steel in 1830, he rediscovered a new chemical element, to which he gave the name vanadium.
Metallic vanadium is rare in nature (known as native vanadium), [52] [53] having been found among fumaroles of the Colima Volcano, but vanadium compounds occur naturally in about 65 different minerals. Vanadium began to be used in the manufacture of special steels in 1896. At that time, very few deposits of vanadium ores were known.
Andrés Manuel del Río y Fernández (10 November 1764 – 23 March 1849) was a Spanish scientist, naturalist and engineer who discovered compounds of vanadium in 1801. He proposed that the element be given the name panchromium, or later, erythronium, but his discovery was not credited at the time, and his names were not used.
Vanadium pentoxide is a commercially important catalyst for the production of sulfuric acid, a reaction that exploits the ability of vanadium oxides to undergo redox reactions. [2] The vanadium redox battery utilizes all four oxidation states: one electrode uses the +5/+4 couple and the other uses the +3/+2 couple. Conversion of these oxidation ...
Vanadium were founded in Milan in 1980 by Stefano Tessarin (guitar), Ruggero Zanolini (keyboards), Domenico Prantera (bass), Lio Mascheroni (drums) and Pino Scotto (vocals). Musically influenced by bands like Deep Purple , Thin Lizzy , Uriah Heep , Black Sabbath and Judas Priest , they had a difficult start due to scarce popularity of the metal ...
The Vanadium Corporation of America was a commercial producer of vanadium, a transition metal and a strengthening additive for steel. The company was founded in 1906 by Joseph M. Flannery and was headquartered in Pittsburgh, Pennsylvania. [1] The company operated several vanadium mines in multiple countries, including Peru.
A mine was established in very short time by the Vanadium Corporation of America. By 1914 75% of the world vanadium ore production was coming from the Minas Ragra in Peru, making the mine the world leading producer of vanadium. [3] With the production of vanadium as side product of uranium mining from carnotite the mine had to close in 1955.
