ABSTRACT:
The evaporation of metal for the production of alloys by the deposition of the components from the vapour phase is carried out in a controllably heated source comprising a melting compartment, in which in operation the metal is melted; a mixing compartment, a constriction in the passage from the melting to the mixing compartment to minimise back mixing of the molten metal, and an evaporation compartment, the supply of metal from the mixing compartment to the evaporation compartment being below the surface of the molten metal. Heating is preferably by electron beam heating.
