The formation process of the 2223 phase synthesis via conventional calcining condition has been systematically investigated using XRD, SEM/EDX, TG/DTA and TMA. The calcining powder prepared at 1073K for 18ks consists of 2201 phase, 2212 phase, Ca2PbO4, CaO, CuO and Sr14-xCaxCu24O41. With increasing a holding time in firing process at 1133K, 2212 phase, Ca2PbO4 and Sr14-xCaxCu24O41 did decrease, and 2223 phase, Ca2-xSrxCuO3 and Bi0.5Pb3Sr2.5Ca2CuOx increased. It was considered that 2223 phase, Ca2-xSrxCuO3 and Bi0.5Pb3Sr2.5Ca2CuOx were formed by reaction with 2212 phase, Ca2PbO4 and Sr14-xCaxCu24O41. The liquid phase was formed from 1113 to 1133K in firing process, and then Sr14-xCaxCu24O41 was drastically formed reaction with the liquid phase and CuO. The reason that needs long term-heat treatment to synthesize 2223 phase with conventional calcining condition is regarded as formation of Sr14-xCaxCu24O41.
