Title (EN) METHODS FOR PRODUCING METAL POWDERS AND METAL MASTERBATCHES
(FR) PROCÉDÉS DE PRODUCTION DE POUDRES MÉTALLIQUES ET DE MÉLANGES MAÎTRES MÉTALLIQUES
Abstract:
(EN) A method for producing a metal powder that combines molten reducing metal and metal halide in a space that is substantially free of oxygen and water, wherein the molten reducing metal is sodium and/or potassium, or aluminum (or magnesium or titanium) and is present in a stoichiometric excess to the metal halide which is a solid or liquid, thereby producing metal particles and salt, removing unreacted reducing metal, optionally removing the salt, and recovering the metal powder, is described. A method for producing a metal masterbatch wherein the molten reducing metal is aluminum, magnesium, and/or titanium and after combining molten aluminum (or magnesium or titanium) and metal halide in the reaction space, substantially removing the produced metal salt to obtain the metal masterbatch which comprises at least a portion of the molten aluminum (or magnesium or titanium) and at least one metal also is described.
(FR) L'invention concerne un procédé de production d'une poudre métallique qui combine un métal réducteur fondu et un halogénure métallisé dans un espace sensiblement dépourvu d'oxygène et d'eau, le métal réducteur fondu étant du sodium et/ou du potassium, ou de l'aluminium (ou du magnésium ou du titane) et étant présent dans un excès stœchiométrique par rapport à l'halogénure métallisé, qui est un solide ou un liquide, ce qui permet de produire des particules et un sel métalliques, d'éliminer le métal réducteur n'ayant pas réagi, d'éliminer éventuellement le sel, et de récupérer la poudre métallique. L'invention concerne également un procédé de production d'un mélange maître métallique, dans lequel le métal réducteur fondu est de l'aluminium, du magnésium et/ou du titane et, après la combinaison d'aluminium (ou de magnésium ou de titane) fondu et d'halogénure métallisé dans l'espace de réaction, le sel métallique produit est sensiblement éliminé en vue d'obtenir le mélange maître métallique qui comprend au moins une partie de l'aluminium (ou du magnésium ou du titane) fondu et au moins un métal.
