Abstract

A chemical spray deposition process (CSD) with nitrate acidic aqueous solution system as starting solution was developed to prepare Bi(Pb)-Sr-Ca-Cu-O superconducting films to high- alumina ceramic substrate. The films possessing superconducting transition with onset above 98 K and the zero-resistance state at 74 K were successfully obtained. By comparing CSD and bulk samples on structure, resistivity, morphology, and Raman spectrum, we conclude that the reaction between film and substrate was the major cause for low T_c.
