Abstract
Single crystals of the superconductor BaPb1-xBixO3 With nominal compositions of x=0.25, were grown by cooling from the melt using an excess of PbO. The superconducting transitions have been measured on the grown crystals as a function of oxygen annealing and sharp transitions with T(conset) at 12 K have been observed. The related perovskite Ba1-xKxBiO3 superconductor (x = 0.4) has been synthesized by a new melt-processing technique using an infra-red image furnace. The melt-processed material on post annealing, is superconducting with T(conset) approximately 25 K. The superconducting properties of these two families of superconductors are presented.
