摘要
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。
Amorphous Bi(Pb)-Sr-Ca-Cu-O strips of (1112) and (2212) types weremade by non-equilibrium solidification of melt-quenching method. On the surfaceof glassy strip, the flexible (2212) superconducting whiskers have been obtained at840-850℃ in a stream of O_2 for a long time. The growth and feature of supercon-ducting whiskers were studied in deteil.
