| Outline of Final Research Achievements |
New superconductive bismuth oxides, (K1.00)(Ba1.00)3(Bi0.89Na0.11)4O12, (Ba0.62K0.38)(Bi0.92Mg0.08)O3 and (Ba0.83K0.17)(Bi0.54Pb0.46)O3 were prepared by hydrothermal reaction. The first one had a double perovskite-type structure with Tc = 31.5K and the second and third ones had a simple perovskite-type structure. The Tc of the second and third ones were 30 and 22.8k, respectively. Their crystal structures were refined by Rietveld method using synchrotron X-ray powdewr diffraction data.
