摘要：

Bi2Sr2CaCu2O8+delta (Bi-2212) superconducting single crystals were prepared using starting materials. With the compositions of Bi:Sr:Ca:Cu = x:2:1:y (x, y = 2-3) by a modified vertical Bridgman method. We could obtain large plate-like single crystal with x = 2 and y = 2, which had a size. of 18 x 5 mm(2). In the single crystal, the FWHM value of the (0010) XRD peak which corresponds to Bi-2212 superconductor was small and about 0.05degrees. We also found that the single crystal showed a sharp transition in resistance-temperature characteristic when it was prepared using the starting materials with the compositions of Bi:Sr:CA:Cu = 2:2:1:3.
