| titleOfInvention | METHOD OF REDUCING ZIRCONIUM |
| abstract | A molten-salt phase contg. the Zr cpd. to be reduced is prepd. and contacted with a liq. metallic phase contg. a reducing metal more electropositive than Zr and a metal solvent less electropositive than Zr. The Zr cpd. is reduced by the reducing metal which passes from the metallic phase to the molten salt phase, and the Zr passes in the opposite direction. The solvent is Zn, Cd, Pb, Bi, Cu or Sn (pref. Zn). The reducing metal is Mg, Na, Cd, or pref. Al. The Zr cpd. is pref. Na2ZrF6. The amt. of Al present is sufficient for the reduction of 85-98% of the Na2ZrF6 to Zr. The cpd. Na2ZrF6 is reduced forming (NaF)1.5.AlF3 which is almost pure and which is then separated from the molten phase. The molten salt phase contains salts other than Zr cpds. The cations of these salts are more electropositive than those of Zr. Part of these cations are selected from alkali metals, alkaline earths, rare earths and Al. The anions of these salts are halogen; Cl or F. |
