Abstract

In this paper, an experiment about the fabrication method of superconductor was made in order to obtain crystal structure by making High T$\sub$C/, superconductor Y$_1$Ba$_2$Cu$_3$O$\sub$x/ to Y$_2$Ba$_1$Cu$_1$O$\sub$x/ of nonsuperconductor phase was added. 211 phase, which can approach crystal structure and growth-orientatoun, was used as seed in the 123 phase which shows the properties of superconductor. Therefore crystal growth effect was able to be attained. And the effect is expected to eleminate thin crack in the growth-process and to improve electrical properties by adding Ag to High T$\sub$c/ superconductor Y$_1$Ba$_2$Cu$_3$O$\sub$x/ combined with Y$_2$Ba$_1$Cu$_1$O$\sub$x/ .
