在O2气体流中加热熔融淬火板，制备了含有高tc相的Bi(Pb)-Sr-Ca-Cu-O超导体纤维晶体。在105k时，纤维的电阻明显下降。在微区x射线衍射仪上检测到高tc相，发现高tc晶体堆叠在低tc片状晶体之间。迄今为止获得的最高Tc（零）值为96 K。
Fibrous crystals containing the high-Tc phase of the Bi(Pb)-Sr-Ca-Cu-O superconductor have been prepared by heating a melt-quenched plate in a stream of O2 gas. The fibers show a remarkable resistance drop at 105 K. The high-Tc phase is detected on a microarea X-ray diffractometer and the high-Tc crystals are found to be stacked between the low-Tc platelike crystals. The highest Tc(zero) value so far obtained is 96 K.
