Ferroniobium and chlorine gas are heated to 600-800 deg.C to form a mixture of (NbCl5)2, Fe2Cl6, Al2Cl6 and SiCl4 gases that are purified by passing through a column of hot NaCl pieces (at 280-300 deg.C). The impurities react with NaCl and collect at the bottom of the column in liquid form, the purified (NbCl5)2 steam is then condensed at below 280 deg.C. The granules of NaCl are of 30-40 mm dia. and are replaced regularly.
