From the superconductor compound (Bi0,8Pb0,2)2Sr2 - Ca2Cu3O10+γ (BSCCO-2223), BSCCO - 2223 superconducting tapes were prepared using the oxide power-in-tube (OPIT) method, using different thermal treatments. By submitting the tapes to high temperatures, high current densities relative to bulk material Jc ≈ 10 A/cm2 - 77 K and B = 0 T and high grain connectivity were obtained, which could be attributed to partial fusion of the compound. Morphology and composition of the packed material were
