Abstract
Procedimiento para la preparación de una composición de polvo de aluminio dispersable, caracterizado porque comprende tratar en una primera etapa una materia de aluminio en partículas triturandola en un medio hidrocarbónico con alrededor de 0,1% a menos de l 5% en peso, basado en el peso del aluminio sometido a tratamiento, de un polvo de resina de polivinilpirrolidona, hasta que se obtiene un tamaño de partícula de aluminio deseado y separar, a continuación, la mayor parte del medio hidrocarbónico para proporcionar una composición de pasta de aluminio conteniendo del 15% a l 30% en peso de medio hidrocarbónico.
