Abstract

Bi_2-x Pb_x Sr₂Ca₂Cu₃O_y superconducting samples with 0<x<0·3 have been synthesized and characterized using X-ray powder diffraction. T_c and superconducting volume fraction have been measured using a.c. magnetic susceptibility, d.c. electrical resistivity as well as X-band microwave surface resistance in the normal state. The data indicate the growth of the high T_c (2223) phase with corresponding reduction of the low T_c (2122) phase with increasing x, up to 0·25. Beyond this value of x there is a slight deterioration of the superconducting behaviour.
