YBa 2 Cu 3 O 7-x films were deposited onto flexible copper substrates by screen printing technique. YBa 2 Cu 3 O 7-x films were prepared from a YBa 2 Cu 3 O 7-x superconductor powder with ethylene glycol. The mixtures were screen printed and then sintered in air at different temperatures: 373, 473, and 573 K. The structural characterization showed the presence of different phases; the proportion of phases in films depends on sintering temperature. Scanning electron microscope images showed that an annealing temperature increase leads to an increase in grain size due to a coalescence process, which promotes the growth of superconductor phases with higher oxygen content.

YBa 2 Cu 3 O 6.962超导体大量丝网印刷沉积的YBa 2 Cu 3 O 7-x薄膜的结构和形态特征。

通过丝网印刷技术将YBa 2 Cu 3 O 7-x膜沉积到柔性铜基板上。由YBa 2 Cu 3 O 7-x超导体粉末与乙二醇制备YBa 2 Cu 3 O 7-x膜。将混合物丝网印刷，然后在空气中于373、473和573 K的不同温度下烧结。膜中相的比例取决于烧结温度。扫描电子显微镜图像显示，由于聚结过程，退火温度升高导致晶粒尺寸增加，从而促进了含氧量更高的超导体相的生长。
