The crystallite size of copper electrodeposits was determined by X-Ray powder diffraction analysis using a General Area Detector Diffraction Solution (GADDS) diffractometer. Crystallite size was calculated for copper thin films which were deposited on a 316 stainless steel rotating cylinder electrode (RCE) in the presence and absence of additive "A". The crystallite size was calculated from a corrected full width at half maximum (FWHM) of the  peak profile using the Scherrer equation. The test of significant difference on crystallite size was derived using Kruskal-Wallis method. It was found that in the absence of the additive the median crystallite size was 426Å, which decreased to 364Å in the presence of the additive. As the additive degraded, the crystallite size increased to a size similar to that observed in the absence of additive.
