Abstract: In this paper, 2201 and 2212 phases as the corresponding precursor of forming 2212 and 2223 phases are discussed,and the constructive process of unit cell of 2201 phase is ascertained by XRD and chemical kinetics method. Subsequently, the process of 2212 and 2223 phases is described by analyzing the order of CuO2 and CaO planes entering in terms of kinetics equation as well as apparent activation energy. In addition, the orientation for preparing 2223 single phase is explored.
