The papers dealing with the effects of electrodeposition conditions on the decisive characteristics of electrolytic copper powder and their mutual relations are reviewed, and a semiquantitative theory based on them is presented. Also, the method for the estimation of the surface energy of disperse deposit formation based on the estimation of a surface area of deposits at different overpotentials is proposed. Then, the values of the surface energy of disperse deposit formation estimated in this way are used for the correlation of the specific surface of a powder to the electrodeposition conditions. The good agreement between the values of the specific surface of a powder determined in this way and those found in the literature is obtained. The apparent density of a powder as one of the decisive characteristics of metal powders is also correlated to the specific surface, and hence, to the electrodeposition conditions. In this chapter, the size of representative powder particle having the same specific surface as a powder is defined and the shape of the particle size distribution curve is analyzed. The problems concerning the effect of the particle shape and structure on the flowability of electrolytically formed copper powder are also discussed.© 2009 by Nova Science Publishers, Inc.
