摘要：

Thick Bi1.4Pb0.6Sr2Ca2Cu3O(x) superconducting tapes, which can flow practically high critical currents, are obtained continuously by the following process: (1) calcined Bi1.4Pb0.6Sr2Ca2Cu3O(x) particles, mixed with paraffin wax, are extruded through a nozzle to align platelike particles unidirectionally; (2) the paraffin wax, used as a matrix for workability, alone is burned out, taking care not to destroy the extruded configuration; (3) the burned out tapes are pressed to realize the denser configuration; and then (4) annealed at 850-degrees-C for 100 h in air.
