Abstract

Un proceso para producir polvos de metal, que tiene un tamaño inferior a 200 nm, que comprende las etapas de mezclar por lo menos una sal de metal con un copolímero no hidrofílico que contiene un óxido de etileno para formar una pasta de sal de metal/copolímero, ycalcinar la pasta a una temperatura entre 300 y 3000°C para expulsar el agua y los orgánicos de dicha pasta, dejando como residuo un polvo con base en metal que tiene un tamaño de partícula menor a 200 nm;en donde dicho copolímero tiene un peso molecular promedio mayor que 400, un contenido de óxido de etileno de 1 a 90 por ciento y un equilibrio hidrofílico-lipofílico (EHL) entre-15 y 15.
