A review on extractive metallurgy of tantalum and

Production of metallic Ta and Nb. The way to yield Ta and Nb as pure metals is ultimately dictated by the form under which they are found in the respective intermediates. The refining of Ta from the potassium heptafluorotantalate is commonly achieved by the reduction of the latter with sodium (Eq. ). To obtain high-purity tantalum, it is recommended that both the salt and the sodium bearing

Tantalum Article about tantalum by The Free Dictionary

Tantalum is almost always found in association with niobium; separation of the two metals is difficult. Major uses of tantalum include electrolytic capacitors, chemical equipment, and parts for vacuum furnaces, aircraft, and missiles. Tantalum was used in the filaments of electric light bulbs and electronic tubes but has been largely replaced by tungsten for these uses. It is often alloyed

US3811867A Process for the recovery of tantalum and

The added aluminum oxide or calcium oxide combines with the silicon oxide and other metallic compositions present to form a slag phase of a new composition which has a melting point 100*-400*C higher than the original slag composition. In the fusion the carbon reduces the tantalum and niobium and other oxides to the respective metals and the higher melting range of the new slag composition
