Abstract

A novel aqueous sol-gel synthesis technique has been refined to prepare heterometallic (Bi_1.75Pb_0.25)Sr₂CaCu ₂O_x and (Bi_1.8Pb_0.33)Sr _1.87CaCu₂O_x (Bi-2212) oxides. The formation of Bi-2212 phase depending on synthesis conditions (duration of annealing, stoichiometry of metals) has been estimated. The synthesized products were characterized by powder X-ray diffraction analysis (XRD) and resistivity measurements. It was demonstrated, that the investigated synthesis conditions only slightly influence on the phase purity and superconducting properties of Bi-2212 phase.
