Abstract
ABSTRACT Electrodeposition is a candidate method for producing fine and pure copper powder , which have a wide range of uses in different fields such as in applications of aerospace , atomic energy , defense , electronics , paints , plastics , cutting tools , ... etc . This work focusing on studying some working variables such as voltage , temperature , copper sulfate concentration , sulfuric acid concentration , circulation velocity and lanoline addition on fineness and producebility of deposited copper powder . Optimum conditions concluded for copper powder fineness were at ( 1.6V , 30 ° C , 25g / L of copper sulfate , 150g / L of sulfuric acid and circulation velocity of 150 rpm . Addition of 0.075g of lanoline increase the fineness of deposited copper powder , but did not affect clearly the dendritic shape of deposited particles .
