摘要：

The critical current density of Ag sheathed (Bi,Pb)-Sr-Ca-Cu-O tapes with thicknesses below 0.2mm exhibiting the 2223 phase has been systematically studied for various compositions and oxygen contents of the surrounding atmosphere. The study also comprises various sequences of the final thermomechanical treatment leading to a textured structure. Critical current densities exceeding 20.000 A/cm2 have been measured at 77K, OT. Due to the large number of parameters involved in the optimization of this system and to the complex formation conditions, a substantial further increase of j(c) in the 2223 phase is still expected. This is particularly important in view of the use of 2223 tapes at 4.2K and high magnetic fields.
