ABSTRACT A silver tube with one open end is packed with a particulate mixture of reactants comprised of Bi2CaSr2CU2O8?x, Ca2CuO3, cupric oxide and lead oxide, the open end of the packed tube is plugged with silver, the re ulting closed tube is swaged to increase the density of the packed mixture, the swaged tube is wire-drawn, uniaxial pressure is applied to the wire orienting the Bi2CaSr2Cu2O8?x crystals with their c- axis parallel to each other forming an initial tape, the inttial tape is fired to convert part of the Bi2CaSr2Cu2O8?x crystals to Bi2-yPbyCa2Sr2Cu3O10?z crystals producing an lntermediate tape containing dilated product, uniaxial pressure is applied to the resulting intermediate tape to remove the dilation in the product, and the pressed intermediate tape is fired to produce a tape comprised of silver enveloping a sintered body of Bi2-yPbyCa2Sr2Cu3O10?z.
