Zusammenfassung:The(1112)and(2212)amorphous strips ofBi(Pb)-Sr-Ca-Cu oxide were prepared bynon-equilibrium solidification of melt-quenchingmethod.A lot of superconducting whiskers havebeen grown up on the strip at 840-860°C in astream of oxygen for 50-150 h,which are usuallyseveral to 10 odd mm in length,several μm in thick-ness and more than 10μm in width.These whiskershave very excellent flexibility.
