The critical current density at 77 K at 0 T and the tensile strength at room temperature of high Tc Bi(Pb)-Sr-Ca-Cu-O and Y-Ba-Cu-O oxides in silver-sheathed tapes prepared by the powder-in-tube method were investigated. The main results can be summarized as follows. (1) The critical current density

The growth mechanism of the high T c phase in the leaded Bi-Sr-Ca-Cu-O system has been studied. It is shown that the crystal growth of the high T c phase takes place with the coexistence of a partial melting phase. A growth mechanism is proposed in which the high T c phase precipitates from the melt
High T c Bi(Pb)-Sr-Ca-Cu-O core/silver sheath superconducting composite tapes with various volume fractions of oxide core (0.05-0.5) were prepared by the powder-in-tube method. The influence of the volume fraction of the oxide core on the strain endurance of the critical current density at 0 T at 77
