摘要：

The unidirectional solidification technology by the zone melting method is performed to obtain the large single domain YBCO. And the interface stability and morphology evolution rules of the metallic crystal growth during the traditional unidirectional solidification are not applicable to the YBCO crystal growth. It was found that the crystallology features of the YBCO crystal itself mainly decide the interface stability theory and the morphology evolution rules of the YBCO crystal growth during the traditional unidirectional solidification. These research results are useful for the study on the mechanism of the YBCO crystal growth. (c) 2007 Elsevier B.V. All rights reserved.
