This thesis surveys the synthesis and analysis of four samples of bulk superconductors of BSCCO with A, B, C and D index. The first three samples was made by solid state reaction method and the last one via sol-gel method. The microwave effect on both samples B and C reviewed. Then the sample B used as base superconductor for wires by PIT method. A sample with Bi 1/89 Pb 0/41 Sr 2/01 Ca 2/23 Cu 3/03 O x stoichiometry during the two-stage calcination at the temperatures of 700 and 800 and sintering at a temperature of 860 ° C for 170 h was prepared, while the B sample with Bi 1/75 Pb 0/35 Sr 2 Ca 2 Cu 3 O x stoichiometry in the one-stage calcination at the temperature 800 and sintering was treated at a temperature of 850 ° C for 240. The C Sample with Bi 1/7 Pb 0/3 Sr 1/9 Ca 2 Cu 3 O x stoichiometry calcinated at the temperature 810 and at a temperature of 850 ° C for 200 h sintered. The last one, D Sample, with Bi 1/85 Pb 0/35 Sr 1/95 Ca 2 Cu 3/05 O 10+X stoichiometry, calcinated during the two-stage at the temperature of 740 and in the one-stage at the 760 and then in the temperature of 825 ° C for 170 h sintered. Then the samples were analyzed by XRD, SEM, magnetic susceptibility, magneto resistance and critical current density were obtained. So that the current density of sample C is higher and sharper than other samples. Finally, the effect of microwave on the sample was observed. The heat shock induced by microwave result in the phase transformation from 2223 to 2212. And the magnetic susceptibility and magneto resistance curves have two-steps behavior and also broadened.
