Use of a new process based on detailed phase diagram studies of the sy
stem Bi2O3-PbO-SrO-CaO-CuO results in formation of nearly single-phase
(Bi,Pb)(2)Sr2Ca2Cu3O10 (2223) ceramics. Different mixtures of defined
precursor were prepared and studied in order to overcome the very slo
w kinetics of the reaction forming 2223. The best results have been ob
tained with mixtures of Bi1.84Pb0.34Sr1.8Ca1.2Cu2O8, Ca2CuO3 and CuO,
and Bi1.84Pb0.34Sr1.7Ca1.3Cu2O8,Sr0.2Ca1.8CuO3 and CuO.
