hydrometallurgisches processes for the manufacture of fine sphaerischem powder from niedrigschmelzenden metals.

摘要

A process for producing finely divided spherical metal low melting temperatures powders comprises forming an aqueous solution metals, forming a reducible solid material from the solution, reducing the solid to metal powder particles, subjecting the metal particles to a high temperature zone to melt a portion of the metal powder particles and to form droplets and cooling the droplets to form essentially spherical metal particles.
