Abstract :
Superconducting oxide materials with nominal composition Bi-Sr-Ca-Cu2O6-δ modified with Ag and Pb were synthesized by the solid-state reaction method. The materials were characterized by powder X-ray diffraction. The transition temperatures are dependent on the heat treatment. The superconducting transition temperatures were observed at 93.4 K and 69 K. Tconset was decreased to 91 K for silver and lead substituted compounds
