摘　　要：本文利用顶部籽晶熔融法(TSMG)成功制备了YBCO单畴超导块材,通过对不同熔融温度.不同生长温区晶体形貌的分析,探索获得了YBCO晶体生长的关键温度参数.结果表明:YBCO晶体生长的最佳熔融温度为1 035℃,生长温区为1 018℃~978℃,该结果为本实验的进一步开展奠定了重要的基础.Single domain YBCO bulk superconductors have been fabricated by the top-seeding melt growth process（ TSMG）. The key temperature parameters of YBCO crystal growth were obtained by analyzing the crystal morphology with different melting temperature and different growth zone. It was found that the optimum melting temperature is about 1 035 ℃ and the growth temperature is ranged from 1 018 ℃ to 978 ℃. These results lay an important foundation for further development of the experiment.
