Annealing at hight temperature ranging from 650℃ to 800℃under higher oxygen pressure will incur the precipitaion of a Ca_2PbO_4-modified phase. and the impurity phase would be decomposed upon annealing under lower oxygen pressure. With the formation of the impurity phase, the sample's mass and resistivity are increased. and the modulated structure is changed from pure Pb-type to pure Bi-type. While the impurity is decomposed, the mass and the resistiviey of the sample are decreased. and the modulated structure is back to original Pb-type. In addition, the proper amount of precipitation of the Ca_2PbO_4-modified phase has a positive influence on both superconductivity and the weak links between the superconducting grains.
