The first A15 phase superconductor was a vanadium compound, V 3 Si, which was discovered in 1952. [78] Vanadium-gallium tape is used in superconducting magnets (17.5 teslas or 175,000 gauss ). The structure of the superconducting A15 phase of V 3 Ga is similar to that of the more common Nb 3 Sn and Nb 3 Ti .
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. [1] Vanadium was first discovered by the Spanish-Mexican mineralogist Andrés Manuel del Río in 1801. He named it erythronium.
Vanadium was discovered in 1801 by the Spanish mineralogist Andrés Manuel del Río. Del Río extracted the element from a sample of Mexican "brown lead" ore, later named vanadinite. He found that its salts exhibit a wide variety of colors, and as a result he named the element panchromium (Greek: παγχρώμιο "all colors").
The Minas Ragra was a large vanadium mine in the Pasco Region of Peru. The deposit was discovered by a United States Geological Survey expedition on November 20. 1905. [1] Members of this expeditions were Donnel Foster Hewett and José J. Bravo In this deposit the mineral patrónite was first discovered by a member of the expedition Antenor ...
Vanadium (named after Vanadís, another name for Freyja, the Scandinavian goddess of fertility) was originally discovered by Andrés Manuel del Río (a Spanish-born Mexican mineralogist) in Mexico City in 1801. He discovered the element after being sent a sample of "brown lead" ore (plomo pardo de Zimapán, now named vanadinite).
titanium-vanadium Known deposits of titanium and vanadium are in the south-west, the east, and south. Titanium is used for commercial, medical and industrial purposes, while vanadium is mainly ...
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.
