METHOD FOR PRODUCING PARTS FROM HIGH-TEMPERATURE SUPERCONDUCTING MATERIAL Russian patent published in 1997 - IPC

Abstract RU 2093927 C1

FIELD: manufacture of various sensors and counters for superhigh-speed computers, cryoelectronic devices, microwave detectors, and the like. SUBSTANCE: method involves mixing of powdered high-temperature superconducting material and molding. Novelty is that polymeric material used for the purpose is powdered polyvinyl chloride taken in the amount of 10-25% of mass of compound obtained; high-temperature superconducting material is powder of formula (Pb_xBi_1-x)₂Ca₂Sr₂Cu₃O_y; molding is carried out at pressure of 105-180 MPa and at temperature of 433-453 K for 5-30 min. EFFECT: improved quality of parts obtained. 1 tbl
