Abstract
A method and apparatus for producing a high-melting-point and high-toughness metal, comprising: reducing a high-melting point and high-toughness metal chloride with an activated metal to form a high-melting-point and high-toughness sponge metal in a reducing vessel arranged sideways relative to a condensing vessel, wherein the condensing vessel is integrally connected to the reducing vessel through a conduit, and at least one of the reducing vessel and/or the condensing vessel is supported so as to move with thermal expansion of said conduit; and measuring a weight-change of the vessel supported so as to move with thermal expansion of the conduit to estimate the degree of progress of a separating and recovering process on the basis of the detected weight-change when nonreacted activated metal and its chloride remaining in the sponge metal formed in the reducing vessel are recovered into the condensing vessel by vacuum separation.
