Abstract

BSCCO (2223) phase superconducting powder was synthesized by organic route: pyrolysis of citrates was used as alternative method to the solid state reaction. Powder with the nominal composition Bi1.84Pb0.35Sr1.9Ca2.1Cu3Ox was synthesized in very short time: 24h including calcination and firing at 858°C with various intermediate grinding steps. Reactions among components were investigated by thermogravimetric and differential thermal analysis. The identification of the reaction intermediates which play a crucial role in the synthetic process was systematically performed .Hot pressing was carried out in order to prepare highly dense superconducting materials and the densification behaviour of the powders extensively studied.
