摘要：

A new procedure, the liquid flow method, is reported for the separation of large YBCO superconducting single crystals from the flux. We used a shallow alumina boat with a slope of 20°-30°. The slope of the boat could be changed without disturbing the temperature. Single crystals up to 5-10 mm have been obtained; the superconducting transition occurs at about 90 K. The liquid flow method is one of the best techniques for a smooth separation of the flux and the detachment of the as-grown crystals from the crucible. © 1990.
