Abstract
PURPOSE:To produce fine particle contained only a little oxide and O2 and having good particle size distribution from a raw material having low purity by making reduction of a halogenide produced from Ta or Nb raw material in gas phase reduction method by the specific condition at low temp. CONSTITUTION:The Ta raw powder sold at a market is set in packing layer 13 in a chloride generating furnace 12 and the atmosphere is sufficiently displaced with the Ar gas. Next, Cl2 gas, carrier Ar gas and secondary Ar gas are supplied into a reactive tube 11 from lines 7, 8, 9 and H2 gas is supplied into the reducing reaction furnace 14 through a line 10 and nozzle 15 so as to come to 30-500mol ratio of H2/Ta, by the prescribed flow rate respectively. Further, chlorinating temp. in the chloride generating furnace 12 is made to the prescribed temp. and the reaction temp. in the reducing reaction furnace 14 is made to 800-1100 deg.C, to start the reaction. Then, the Ta raw powder is chlorinated and volatilized in the packing layer 13 and the generated chloride gas is introduced to the reducing reaction furnace 14 with the carrier Ar gas and reduced with the H2 gas to produce the Ta fine particle and HCl gas, and the Ta fine particle is collected with recovery filter 16.
