For the Ag-sheathed BijS CaCiijOs tapes, the high Bi2Sr2CaCu2Os phase purity with an appropriate oxygen concentration and excellent grain alignment are responsible for high critical currents. Many fabrication parameters influence the Bi2Sr2CaCu2O8 phase content and microstructure of the tapes, which have been investigated by many researchers. In this paper, we present results of AgMg-sheathed Bi2SrjCaCu2Os heat treatment optimization and characterization. With the help of physical analytical methods such as ESEM, and XRD, the melt temperature is related to the transport measurements.
