<p>An apparatus and a method for producing purified refractory metal from a chloride thereof, comprising: a conversion/ evaporation chamber (1), defined by a first substantially cylindrical vessel means (2) and a first detachable top (3) thereover, said top comprising therewithin an axially extending cell (6) 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 (14) and a water jacket arranged close to said cell (6) 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 (1), a closure arranged around- and movable together with said tube for regulating the opening of the cell, a furnace means (4) which surrounds to heat said chamber (1), a condensation chamber (24), defined by a second substantially cylindrical vessel means (25) and a second detachable top (26) thereover, said top having a cavity to serve as a path (31) for incoming vapor, and a degassing means (32) connected thereto, a cooling means for the condensation chamber (24) by passing water therealong, a heatable duct (16) 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.</p> |
