ABSTRACT:
A process for preparing alloyed or non-alloyed, reactive metals by reaction of halides thereof, in particular chlorides, with a reducing agent at a temperature higher than the melting temperature of the metal to be developed, comprises solidifying the developed metal while maintaining in the reaction zone wherein the reduction proceeds, a layer of this metal in the liquid state, at a temperature higher than the boiling or sublimation temperature of the other reaction products at the pressure at which the reduction develops, these other reaction products being substantially continuously discharged in the gaseous state.
