PROCESS OF MANUFACTURE OF COMPOSITE WIRE FROM SUPERCONDUCTING BIMETAL OXIDE Russian patent published in 1995 - IPC

Abstract SU 1792187 A1

FIELD: electronics. SUBSTANCE: mixture composed of Bi2O3, SrCO3, CaCO3 and CuO components is additionally injected with PbO or SbO. Then composition is synthesized at temperature of 820-830 C in air or in mixture of oxygen with argon. Produced composition (Bi1,7Pb0,3)Sr2Ca1Cu2O8+δ or (Bi1,7Sb0,3)Sr2Ca1Cu2O8+δ is ground to powder. Powder is put to thermal treatment at 600-650 C for the course of 60 min in inert atmosphere. EFFECT: facilitated manufacture of composite wire. 1 tbl
