The laser floating zone (LFZ) method has been used to grow (Bi,Pb)-Sr-Ca-Cu-O superconductor fibers from solution-derived ceramic precursors (nominal Bi{sub 1.8}Pb{sub 0.35}Sr{sub 1.87}Ca{sub 2}Cu{sub 3}O{sub {ital x}}), prepared under different sintering conditions. The as-grown LFZ fibers were semiconducting. After annealing at 855 and 800 {degree}C in air, the fibers were metallic. A second anneal at these temperatures optimized the superconducting properties of the fibers ({ital T}{sub {ital c}} (midpoint)=111 K and {ital T}{sub {ital c}} (zero)=106 K). The LFZ-grown fibers contain highly oriented superconductor grains their electrical properties depend strongly on precursor thermal processing.
