Abstract
The microstructure and superconducting properties of high-T(c) superco nducting materials Bi2-xPbxSr2Ca2Cu3O10+y with variable amounts of lea d (x = 0.2, 0.3, 0.4 and 0.5) have been studied. Nearly single-phase s amples were prepared for x = 0.3, 0.4 and 0.5. There is some optimal c oncentration of Pb around x = 0.3 for which the electrical resistivity is minimal, the transport critical current density J(c) is maximal an d the magnetization decreases more quickly with decreasing temperature .
