✦ Synopsis

Needle-like (Cu~-x Srx)CuOy solidified around 930°C and plate-like Bi(2201) formed by peritectic reaction of (Cu~-xSrx)CuO, and liquid phase below 890"C. Solidification process finished at about 865~3. Bi ( 2212) was formed by a solid state reaction of Bi ( 2201) and (Cu l-xSrx) CuOy. Bi (2223) appeared only in a long time sintering. Grains alignment was observed in the region near surfaces of bulk samples, among which Bi (2201) showed sharpest and narrowest grains alignment, and Bi (2223) exhibited rather blunt and wide grains alignment.
