The cleaned titaniumniobiumtantalum oxichloride gas is then cooled to a liquid and distilled to separate out lowboiling titanium chloride gas whereafter the niobiumtantalum oxichloride gas is further chlorinated to produce NbCl 5 and TaCl 5 These chlorides are fractionally distilled and the niobium chloride subsequently reacted with steam
Apr 14 2019 · Additionally tantalum ore always contains a considerable amount of niobium and a lot of energy is required to remove niobium during the tantalum refining process The problem is that niobium and tantalum have similar chemical characteristics which makes refinement difficult However the tantalum used in capacitors is free of niobium
