Samples of nominal composition (Bi2\_xSbx)Sr2CaCu2Oy (0.1 <x<0.3) are investigated. X-ray diffraction and electron diffraction show that the (Bi2\_ xSbx) Sr2CaCu20~ system has a monoclinic phase with the lattice parameters a = 21.73/k, b = 5.76 โข ~, c = 19.32 ,~ and/3 = 95.0 ยฐ, except for the tetrag
The superconducting phase with mixed TI and Bi, namely (Tlo.55Bio.45)Sr2CaCu20y, was synthesized and characterized. Synthesis conditions were studied, and this phase, (TI,Bi)-1212, was found to form preferentially to (TI,Bi)-1223 when Sr was present with no Ba present. X-ray powder diffraction with
