Preparation of the High-Tc Superconductive Bi-Pb-Sr-Ca-Cu-O Film by Pyrolysis of Organic Acid Salts

Abstract
The high-T c superconductive Bi-Pb-Sr-Ca-Cu-O film on Ag substrate was prepared by the pyrolysis of organic acid salts. The temperature for the high-T c phase formation was 830–835°C in air. The film heated at 832°C contained a large amount of the high-T c phase (2223 phase).
