Influence of Y2BaCuO5 Particles Distribution in Melt-textured Y-Ba-Cu-O Bulk Superconductor on the Superconducting Properties
Source abstract
Abstract
采用顶部籽晶熔融织构法制备了Y-Ba-Cu—O（YBCO）准单畴超导块材，研究了Y2BaCuO5（Y211）粒子在块材中的分布及其对临界电流密度（上）和磁悬浮力性能的影响．扫描电子显微镜（SEM）观察发现，Y211颗粒在准单畴超导块材中的分布是不均匀的．实验结果表明，Y211平均粒径的大小与样品的磁悬浮力和临界电流密度成反比，Y211相粒子在母体中的分布越均匀，粒子平均粒径越小，越有利于提高临界电流密度和磁悬浮力．对于Φ20mm的YBCO单畴块材，磁悬浮力可以达到33N（77K，0．55T），临界电流密度达到6．6×10^4A／cm^2．
