Abstract
Metals and/or metallic compounds are condensed from a vapor in a reaction vessel into a condenser, the condensate initially solidifying to block an outlet at the bottom of condenser; subsequent operation of heating stages from the top to the bottom of the condenser to melt the solidified condensate ensures that, as the outlet becomes unblocked, the whole melt flows into a mould.
