用熔体淬火非平衡凝固方法制备非晶态Bi(Pb)-Sr-Ca-Cu-O(1112),(2212)基材,在流通O_2气氛中经840—860℃长时间保温,生长出柔性(2212)超导单晶晶须,仔细研究了晶须生长及形貌特性。
The amorphous Bi (Pb) -Sr-Ca-Cu-O (1112) and (2212) substrates were prepared by melt quenching and non-equilibrium solidification. The substrates were incubated in a flowing O 2 atmosphere for 840-860 ℃ for a long time, Flexible (2212) superconducting single crystal whiskers, carefully studied whisker growth and morphology.
