摘要

在顶部籽晶熔渗生长工艺(TSIG)的基础上,采用一种新的装配方式制备单畴Gd-Ba-Cu-O(GdBCO)超导块材,并对所得样品的形貌、微观结构以及超导性能进行了研究.结果表明,应用新的装配方式可以提高液相源块的支撑能力,有效避免样品在热处理过程中的倾斜或坍塌现象,从而提高了样品制备过程的稳定性和可重复性.此外,应用新的装配方式还有助于GdBCO样品的完整生长.

Based on the top seeded infiltration and growth technique (TSIG), a novel configuration was employed to fabricate single-domain Gd-Ba-Cu-O (GdBCO) bulk superconductors. And the morphology, microstructure, and superconducting properties of the products were investigated in detail. The results indicate that, employing the novel configuration can increase the supporting ability of the liquid source pellet, and the slope or collapse of the sample during the heat treatment process can be effectively avoided, thus the stability and repeatability of the experiments are advanced. In addition, the novel configuration also contributes to the complete growth of the whole bulk.
