โœฆ Synopsis

The effect of F doping in the (Bi, Pb)-Sr-Ca-Cu-0 system has been investigated by resistance and AC susceptibility measurements. The influence of fluorine on the forming process of superconducting phases and the superconducting properties are shown, and the role of fluorine in the Bi system superconductors is discussed. The effect of the heat treatment of the F doped samples has also been studied. The results indicate that F doping promotes the forming of 2223 phase and increases the bulk r,.

The effect of Ag-doping and of heat treatment on the superconducting properties have been investigated for sintered Bi-(Pb)-Sr-Ca-Cu-O ceramics consisting of the high-T c ( 2223) phase, where the samples were cooled at different rates immediately after the sintering. For undoped samples the impurity
