Scanning electron microscopy, energy dispersive x-ray analysis, (including x-ray dot mapping), x-ray diffraction and computer based image analysis have been used to study non-superconducting secondary phases that evolve during the processing of (Bi,Pb){sub 2}Sr{sub 2}Ca{sub 2}Cu{sub 3}O{sub x}/Ag composite superconductors. These investigations have provided new information and insights about specific alkaline earth cuprates (AECs) and lead-rich phases. We can conclusively identify (Ca,Sr){sub 2}CuO{sub 3}, (Ca,Sr){sub 14}(Cu{sub 24})O{sub 41}, and CuO phases, the alkaline earth plumbates, and a (Bi,Pb)-Sr-Ca-Cu-O 3221 phase with a wide range of Pb/Bi ratios. These techniques also help in differentiating voids from secondary phases and alkaline earth plumbates from the lead-rich 3221 phase.
