摘要：

An ultrasonic spray-pyrolysis process has been used to prepare an homogeneous T10.5Pb0.5Sr2CaCu2Ox high-temperature superconductor. Depending on experimental conditions, the grain morphology changes from platelet to cauliflower-like, contrary to the three copper layers series. The (Tl/Pb)-Sr-1212 phase has remarkable stability and does not decomposed before melting. The critical temperature onset, about 80 K, is similar to that for samples prepared by the usual sintering methods. (C) 1998 Elsevier Science Ltd.
