The flowsheet for preparation of pure tantalum and niobium oxides was developed.
History. Named after Tantalos, a Greek a mythological character, father of Niobe.Discovered in 1802 by Ekeberg, but many chemists thought niobium and tantalum were identical elements until Rowe in 1844, and Marignac, in 1866, showed that niobic and tantalic acids were two different acids. The early investigators only isolated the impure metal. The first relatively pure ductile tantalum was ...
