Abstract
A method and an apparatus for condensing to the liquid state vapors of a metal having a melting point of between 500.degree. and 850.degree. C. in a double envelope container. The pressures between the two faces of the inner envelope of the container are adjusted to be in equilibrium, and the outer face of the inner envelope is cooled in such a way as to keep the inner face temperature substantially constant in the vicinity of the solidification temperature of the metal. The invention is applicable in particular to condensing magnesium vapors.
