PCT No. PCT/FR80/00187 Sec. 371 Date Aug. 21, 1981 Sec. 102(e) Date Aug. 21, 1981 PCT Filed Dec. 22, 1980 PCT Pub. No. WO81/01811 PCT Pub. Date Jul. 9, 1981.Metal in the form of granules is solidified from the molten state by forming a jet of molten metal which is caused to pass through a vibrating orifice in order to divide the jet into individual drops and causing solidification of the drops by cooling so as to form the granules. The drops of the jet are caused to fall from the vibrating orifice under the action of gravity through an inert gas atmosphere which is maintained at a temperature below the solidification temperature of the molten metal. In the case of reactive metals, the jet is formed by withdrawal from a mass of molten metal maintained in contact with a bath which is not miscible with the molten mass and selectively dissolves the derivatives produced in the event of oxidation. |
