The present work has tried successfully to cement the copper-tin composite powders from sulfate solutions of Cu and Sn at pH 0. 12 to 1. 2%. The composite powders with copper compositions of 91. 2% and 79. 9% were obtained, respectively, for the theoretical corresponding compositions of 90% and 80%. Thus cemented higher copper content powders are of cubic shape, while increasing contents of tin tends to distort the cubic shape. The rate of copper cementation is enhanced by the increasing pH values of the initial solution.
