Abstract
Polycrystalline samples of high temperature superconductivity of the type 2223, Bi2-xTlxSr2-yBayCa2Cu3O10+ have been prepared by using solid state reaction process. The influence of the substitution of Tl for Bi and Ba for Sr have been studed with different rates (x=0.1-0.4) and (y= 0.1-0.4) at variable sintering temperature, sinterinr time and annealing at 850ºC for 24 h, at average heating 2ºC/min. The best Tc value obtained for the compound is x=0.3,y=0.3 . The x-ray data of all superconductor samples showed a tetragonal structure with a high ratio of Bi-2223 superconducting phase and the resistivity measurements were done using the electrical resistively instruments.The substitution of Tl by Bi and Ba by Sr increases the grain size of the superconductingphase and the density of the pellets. Also give a best value of Tc =133 K respectively
