The microanalysis by EDAX and XPS is used to identify elements and their valences of the initial growth sites of nodular copper particles on electrodeposited copper.Crystal orientation and the copper sheet cut out along the growth axes of nodular copper particles are also studied by EDAX and XPS.It shows that the adhesion of some suspended slime, such as copper and silver corpuscles, oxides of arsenic,antimony,bismuth and copper, sulfides of copper, makes crystal face(220) be preferred orientation and causes the growth of nodular copper particles. Nonconductor corpuscles such as silicates, calcium and magnesium sulphates would not produce nodulation and are occluded in electrodeposited copper.
