The(1112)and(2212)amorphous strips of Bi(Pb)-Sr-Ca-Cu oxide were prepared by non-equilibrium solidification of melt-quenching method.A lot of superconducting whiskers have been grown up on the strip at 840-860°C in a stream of oxygen for 50-150 h,which are usually several to 10 odd mm in length,several μm in thick- ness and more than 10μm in width.These whiskers have very excellent flexibility.
