Abstract It has been found that the Pb-3222 phase sample could been synthesized in Ce-free Pb-Sr-La-Gd-Cu-O system and the nearly single-phase samples can be obtained within a limited composition. Then, among the nearly single-phase samples, a sample with a nominal composition of Pb2Sr1.4La0.7Gd1.9Cu3O z shows a diamagnetic signal with an onset around 20 K. The superconducting behavior is supposed to arise from the Pb-3222 phase.
