ABSTRACT:
An apparatus and a method for producing purified refractory metal from a chloride thereof, comprising: a conversion/evaporation chamber, defined by a first substantially cylindrical vessel means and a first detachable top thereover, said top comprising therewithin an axially extending cell with an opening at a bottom thereof, a cavity with a flanged outlet to serve as a path for effluent vapor, further, a gas jacket and a water jacket arranged close to said cell and cavity for temperature control, and a valve arranged in the cavity for regulation of vapor flow, a tube so arranged as to movable vertically and to extend along the axis of the top for feeding the chloride to magnesium as fused and held in said chamber, a closure arranged around and movable together with said tube for regulating the opening of the cell, a furnace means which surrounds to heat said chamber, a condensation chamber, defined by a second substantially cylindrical vessel means and a second detachable top thereover, said top having a cavity to serve as a path for incoming vapor, and a degassing means connected thereto, a cooling means for the condensation chamber by passing water therealong, a heatable duct in flanged connection with the outlet of the cavity over the conversion/evaporation chamber and extending to the cavity over the condensation chamber so as to provide a continuous passage for vapor from the former to latter chambers, said first and second vessel means further comprising, each, a cylindrical member of a substantially common geometry such as to support metallic product and to allow joint thereof to respective tops with a fastening means compatible with each other.
