A novel aqueous sol-gel synthesis technique has been refined to prepare heterometallic (Bi1.75Pb0.25)Sr2CaCu2Ox and (Bi1.8Pb0.33)Sr1.87CaCu2Ox (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 super conducting properties of Bi-2212 phase.
