Difference Between Vanadium And Niobium
Niobium and tantalum come in many different forms such as sheet, foil, insulated wire, powder, rod, and tube and the niobium minerals usually contain both niobium and tantalum as it is difficult to separate them due to the chemical similarities between the two. The major uses for niobium and tantalum are in chemical processing, lighting, and in …show more content…
Del Rio accepted the claim issued by the French chemist, as he believed himself to be inaccurate. Solid support of del Rio's identification came years later, in 1931, when it was determined, by Fredrich Wöhler, that the previous work of del Rio, and his "brown lead," was correct and he did originally discover the element vanadium. This fact was only ascertained after being discovered anew by Nils Gabriel SefstrÖm. If only del Rio had known that, he was correct; I would be reporting on erythronium. Instead, in 1831 Nils Gabriel SefstrÖm, a Swedish Chemist, isolated a new oxide while working with iron ores. After several changes, the element name stands with SefstrÖm's selection, which is in honor of a Mythological Scandinavian goddess of beauty, Vanadis. SefstrÖm so named the element this due to the beautiful, multicolored compounds; vanadis refers to beauty and fertility.
Still many years later, in 1867, Henry Enfield Roscoe isolated metallic vanadium when he reduced the vanadium chloride (VCl3) with hydrogen but it wasn't until still many more years later before finally a yield of pure vanadium (of ninety-nine and one-third to ninety-nine and one-eighth percent purity) was achieved. Natural vanadium is a combination of two isotopes ^50V and ^51V with
