Superconducting compound Bi 2 Sr2- x Y x Ca 2 Cu 3 O 10+δ were Synthesized by method of solid state reaction, at 1033 K for 160 hours temperature of the sintering at normal atmospheric pressure where substitutions Yttrium oxide with Strontium. When Y2O3 concentration (0.0, 0.1, 0.2, 0.3, 0.4 and 0.5). All specimens of Bi 2 Sr 2 Ca 2 Cu 3 O 10+δ superconducting compounds were examined. The resistivity of electrical was checked by the four point probe technique, It was found that the optimum and maximum transition temperature T c = 125°K. The crystal structure studied by using XRD analysis and it was showed that the all specimens have tetragonal structures. Bi-2223phase increase by increasing Y 2 O 3 concentration up x=0.4, The increasing addition Yttrium oxide concentration produce increasing in high-phase (Bi-2223) and c lattice parameter.
