| 中文摘要 | The contamination by alumina crucible and the effect of Al impurity on critical temperature T-c of Bi-2212 single crystals were investigated systematically. The results indicate that the concentration of ill impurity in the crystal due to the corrosion of alumina crucible is 0.046 per formula unit for undoped Bi-2212 single crystal. The maximum value of Al concentration in the crystal is 0.115 per formula unit for Al-doped one. T-c of the Bi2.20Sr1.95Ca0.80Cu2-xAlxOy single crystals decreases from 93 to 83 K with the increase of Al content x ranging from 0 to 0.115. Besides, a reaction product of the melt with the alumina crucible was found, and its composition was examined to be (Sr0.62Ca0.38)AlO2.5 approximately. (C) 1999 Elsevier Science B.V.
