Fabrication of Thick Bi1.4Pb0.6Sr2Ca2Cu3Ox Superconducting Tapes by an Extrusion Method Using Paraffin Wax

Thick Bi1.4Pb0.6Sr2Ca2Cu3Ox superconducting tapes, which can flow practically high critical currents, are obtained continuously by the following process: (1) calcined Bi1.4Pb0.6Sr2Ca2Cu3Ox 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°C for 100 h in air.
