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 f lowing oxygen, is reported. The thermal behavior of the glassy samples (studied by DTA, XRD, and SEM techniques) was found to be dependent o n the dopant as well as on its concentration. The Bi2Sr2CaCu2Ox (2212 phase) whiskers were grown only from the Ga-doped system annealed at 8 55 degrees C. The dependence of the mechanism of the whiskers' growth on the dopant is also discussed.
