Abstract

Es wird ein Verfahren zur Herstellung von Metallen oder Metallegierungen beschrieben, wobei aus einem wasser­ stoffhältigen Plasmagas und dampfförmigen Metallhalogen­ iden, insbesondere Titantetrachlorid, eine bewegte Plasma­ strahlreaktionszone hoher Temperatur gebildet wird, in der die Metallhalogenide reduziert werden und in flüssiger Form anfallen. Das flüssige Metall wird in eine unterhalb der Reaktionszone angeordnete Kokille geleitet und aus dieser kontinuierlich abgezogen. Zusätzliche Wasserstoffströme, die die Plasmastrahlreaktionszone umgeben, können vorge­ sehen werden, um das bei der Reaktion entstehende HCl und nicht umgesetzte Metallhalogenide abzuleiten. It is a process for the production of metals or Metal alloys described, being from a water substance-containing plasma gas and vaporous metal halides iden, especially titanium tetrachloride, a moving plasma beam reaction zone of high temperature is formed in the the metal halides are reduced and in liquid form attack. The liquid metal is in a below the Reaction zone arranged and passed from this mold deducted continuously. Additional hydrogen flows that surround the plasma jet reaction zone, can pre to see the HCl and derive unreacted metal halides.

Die Vorrichtung für die Durchführung des Verfahrens besteht aus einem Reaktionsgefäß (2), in welches von oben durch eine Plasmalanze (4) ein Gemisch des Plasmagases und der dampfförmigen Metallhalogenide eingeleitet wird. Im unteren Teil des Reaktionsgefäßes befindet sich das reduzierte Metall, der Metallsumpf (12), der die Gegenelek­ trode bildet. The device for performing the method consists of a reaction vessel (2) into which from above through a plasma lance (4) a mixture of the plasma gas and the vaporous metal halide is introduced. This is in the lower part of the reaction vessel reduced metal, the metal sump (12), the counterelek trode forms.
