　　A combined heat treatment was designed expecting to improve the microstructure of Bi-2223/Ag/Ni tapes.Samples were sintered in air for 50 h firstly,and then sintered at a reduced oxygen partial pressure of 0.085 atm.The effects of varying oxygen partial pressure on the formation and grain size of Bi-2223 phase were explored.
