The effect of sintering temperature on the crystal growth of the Bi-2223 phase in multifilamentary tape

Record type: Article

Bi-2223 tapes with 37 filaments, Ag–Mg–Ni alloy outer sheath and pure Ag inner sheath were heat treated in 7.5% O2 at different temperatures for 40 h. XRD of etched samples for increasing sintering temperature from 798 to 847 °C showed an increase of eightfold in the absolute intensity of the Bi-2223 (0 0 10) peak, without substantial decrease in the intensity of the Bi-2212 (0 0 Image) peak. These changes were correlated with the amount of liquid phase obtained from the Bi-2201 (0 0 8) peak. Optical microscopy also suggested an important role of the liquid phase by revealing significant changes in the morphology of Bi-2223 grains with increasing sintering temperature.
