Abstract

The effect of the doping on the growth and superconducting properties of whiskers in the Bi-Sr-Ca-Cu-X-O system (where X = Na, B, Ga, and Pb, respectively). prepared by heating a glassy melt-quenched plate in flowing oxygen, is reported. The thermal behavior of the glassy samples (studied by DTA, XRD, and SEM techniques) was found to be dependent on the dopant as well as on its concentration. The Bi2Sr2CaCu2Ox (2212 phase) whiskers were grown only from the Ga-doped system annealed at 855 °C. The dependence of the mechanism of the whiskers' growth on the dopant is also discussed.
