| Abstract | The stable superconducting phase with T-c 110 k has been prepared in samples of nominal composition (Big-x Pb-x) Sr-2 Ca-2 Cu-3 O-r and (Big-x Pb-x)Sr-2 Ca-2 Cu-2 O-r with T-c 106. K-3 has been determined in the sample of nominal compositions (Bi1-8Pb0.2)Sr-2 Ca-2 Cu-5 O-y. It is a nine deckter perovskite arrangement by incorporating two extra layer CaCuO2, space group D1/2h - Pmmm was assigned. Adding Pb is in Bi site, and atomic radius and atomic valence in Bi site was modified, so that it is able to stabilize crystal structure and progress superconducting properties. |
