摘要：

By passing a flexible copper wire through the molten BiPbSrCaCuO system at a high constant speed, long lengths of composite wires were prepared. Depending on the pulling speed and the temperature of the melt, a coating with different microstructure and thickness from less than ten to several tens of microns can be obtained. The short samples cut out of the composite wires thus obtained were annealed in air in a preheated furnace. After relatively short-time annealing at 800°C, both resistivity and d.c. magnetization versus temperature measurements show indications of onset of superconductivity in the 110-115 K region; zero resistance was achieved in the range 65-70 K. © 1990.
