【Abstract】 In this paper, we have studied the different ways of influencing the BiSrCaCu₂O_y （1112） which are formed by 80-90K or 100-110K superconducting phase The R-T relation and magnetic hystersis are performed. The structure and component are analyzed by X-ray powder diffraction and by scanning electron microscope respectively. Our conclusion is that the proper high temperature maintained for a long time and quenching during sintering samples are advantageous to the growth of the high temperature jphase.更多还原
