Substitution of Bi in (Tl2-x Bix Ba2 Ca2 Cu3 O10) compounds and the effect on its structural and electrical properties

The resistivity to electricity of the high temperature super conductivity Tl2-x Bix Ba2 Ca2 Cu3 O10 was measured at temperatures between (90 to 330) K. The results displayed that the critical temperature of the Zero resistivity rises from (121 to 146) K once the Bi concentrate - ion raised from 0.1 to 0.5. The structure of the Tl2 Bi2 Ba2 Ca2 Cu3 O10 compound has also been examined by XRD technique. The examination defined that the compound structure type is tetragonal where a=b=5.36Ao and c=36.09Ao, furthermore the value of C-axis rises to 37.8Ao when up to 0.5 raised.
