Abstract: Among the several families of high Tc ceramic superconductors, (Bi,Pb)-Sr-Ca- Cu-O system has attracted the attention for the fabrication of super conducting wires and tapes. In this system, the identified superconducting phases are Bi-2201 (Tc = 10K), Bi- 2212 (Tc = 85K) and Bi-2223 (Tc =110 K). Of these, the Bi-2223 phase offers a large temperature window for 77K operation. Considerable effort has been made by various groups during the last few years to fabricate super conducting tapes with Bi-2223 phase by several techniques. The powder-in-tube (PIT) technique has assumed greater significance because of the superior performance of the processed tapes, particularly with respect to the transport properties and the case of the fabrication of long flexible tapes. Such tapes are being produced with consistently high critical current values of around 30,000 A/cm2 at 77K and zero field for short length. Producing superconducting materials, particularly high-temperature superconductors (HTS), is expensive
