ABSTRACT:
A method and apparatus for continuously producing metals such as zirconium, hafnium, titanium, niobium, vanadium, silicon and tantalum. The corresponding metal halide is reacted with a metallic reducing agent such as aluminum, calcium, magnesium and sodium in a reactor where the reaction takes place at a temperature where the metal reducing agent is below its vaporization temperature and where the metal halide is above its vaporization temperature. The metal formed by the reaction is recovered from the reactor by collecting it in a pool of molten product metal contained in a cold wall induction heated receptacle in the reactor from which the metal product is removed.
