摘要：

This study demonstrates the preparation of screen printed Bi-(Pb)-Sr-Ca-Cu-oxide superconducting films starting from a paste, based on spray dried nitrate solutions. The spray dried precursor powder was studied using TGA-DTA and XRD. It is shown that decomposition to oxides occurs at temperatures more than 200 degrees C lower than those in the respective oxide/carbonate mixture. The thick film properties were studied using XRD, SEM-EDAX and electrical resisitivity measurements. The films, coated on alumina substrates, showed clear superconducting transition below 60K, but did not reach zero resistivity. Films coated on alumina with a ZrO2 buffer layer and sintered at 835 degrees C showed T-c, 0 up to 77 K.
