Abstract

Métodos para la fabricación de polvos metálicos finos a partir de compuestos de carboxilatos metálicos tales como compuestos de oxalatos metálicos. El método incluye descomponer las partículas del compuesto de oxalato metálico calentando hasta una temperatura de descomposición en la presencia de un hidrógeno gaseoso diluido para descomponer el compuesto de oxalato metálico, y formar un polvo metálico fino calentando hasta una temperatura de refinación más alta para extraer contaminantes del polvo mecánico. El método puede incluir la conversión de un compuesto metálico que no es un oxalato en un oxalato metálico hidratado y la deshidratación del oxalato metálico hidratado antes de su descomposición al metal. El método puede se aplicado a la producción de una amplia variedad de metales, y es particularmente aplicable a la producción de metales de tierras raras de alta pureza y de un tamaño de partícula fino.
