The choice of the conditions to receive the electrolytic zinc powders for metal-rich compositions

Abstract

The paper presents a method of obtaining high-dispersed zinc powders by electrolysis and comparison of the properties of zinc-rich compositions prepared using as a pigment zinc powders obtained by different methods. Measurements have shown that the electrical conductivity of zinc-rich coatings containing electrolytic zinc powder, not inferior to the conductivity of the film with powder PZHD-0 obtained by the method of evaporation-condensation, despite the significant difference in the amount of zinc pigment. On the basis of the received data we can conclude that the use of electrolytic zinc powder as a pigment will significantly save zinc.
