METHOD FOR PREPARATION OF A METAL POWDER
Document Type and Number:
WIPO Patent Application WO/2016/023461
Kind Code:
A1
Abstract:
Provided is a method for preparation of a metal powder; metal nitrate or metal sulfate is combined with aqueous ammonia to produce an ammonia-containing metal-complex salt solution; the described solution is then quantitatively jet-mixed with a hydroxylamine-containing compound solution, and reacted under intense stirring; a dispersant solution is added during the reaction process, and after the reaction is complete, the solution is separated by centrifugation to yield the metal powder. The method effectively controls the rate of reaction during the process of production of the metal powder; at the same time, crystal nucleation growth rate and dispersion are also controlled well by the method, and the metal powder produced has very good crystallinity and sphericity, and high tap and high dispersion.
