HIGH J_c Ag-Bi-Pb-Sr-Ca-Cu-O SUPERCONDUCTORS

Bi2Sr2Ca2Cu3Oy-Agx, Bi1.7Pb0.3Sr2Ca2Cu3Oy-Agx and Bi1.7Pb0.3Sr2Ca2Cu3.2Oy-Agx were prepared by the solid state reaction. Analytical reagents AgNO3, PbO, Bi2O3, SrCO3, CaCO3 and CuO were used as starting materials. Appropriate quantities of the starting materials were mixed, ground and fired at 800°C...

Zusammenfassung:Bi2Sr2Ca2Cu3Oy-Agx, Bi1.7Pb0.3Sr2Ca2Cu3Oy-Agx and Bi1.7Pb0.3Sr2Ca2Cu3.2Oy-Agx were prepared by the solid state reaction. Analytical reagents AgNO3, PbO, Bi2O3, SrCO3, CaCO3 and CuO were used as starting materials. Appropriate quantities of the starting materials were mixed, ground and fired at 800°C for 12 h, reground, pressed and sintered for a
