Title
(EN) METHOD OF MAKING METALS AND OTHER ELEMENTS
(FR) PROCEDE DE PRODUCTION DE METAUX ET D'AUTRES ELEMENTS
Abstract
(EN)
A method of producing a non-metal element or a metal or an alloy thereof from a halide or mixtures thereof. The halide or mixtures thereof are contacted with a stream of liquid alkali metal or alkaline earth metal or mixtures thereof in sufficient quantity to convert the halide to the non-metal or the metal or alloy and to maintain the temperature of the reactants at a temperature lower than the lesser of the boiling point of the alkali or alkaline earth metal at atmospheric pressure or the sintering temperature of the produced non-metal or metal or alloy. A continuous method is disclosed, particularly applicable to titanium.
(FR)
Procédé de production d'un élément non métallique, d'un métal ou bien d'un alliage de ces derniers à partir d'un halogénure ou de mélanges d'halogénures. Selon ce procédé on met en contact l'halogénure ou le mélange d'halogénures avec un écoulement de métal alcalin liquide, ou de métal alcalino-terreux ou encore de mélanges de ces derniers dans une quantité suffisante pour que l'halogénure se transforme en un non métal, en un métal ou en un alliage et pour maintenir la température des réactants à une température inférieure à la plus basse température d'ébullition du métal alcalin ou du métal alcalino-terreux à la pression atmosphérique ou la température de frittage du non métal, du métal ou de l'alliage produit. On décrit un procédé en continu s'appliquant tout particulièrement au titane.
