Method for manufacturing high-temperature superconductor of mercury (Hg)-barium (Ba)-calcium (Ca)-copper (Cu)-oxygen (O)

摘要

The present invention relates to a method of manufacturing a high-temperature superconductor used in electronic devices such as computers, a geological exploration apparatus, a medical instrument, and a military detector, and more particularly, to a method of manufacturing a superconductor of Hg-Ba-Ca-But it has its purpose.;The present invention relates to a method for producing a Hg-Ba-Ca-Cu-O system high-temperature superconductor, which comprises reacting BaCaCu₂O_{5 + X}Compound and CaCuO_{2 + x}Preparing a compound; The Ba₂CaCu₂O_{5 + X}Compound and mercury oxide are mixed at a molecular ratio of 1: 1 and then reacted at a temperature of 800-820C and a mercury vapor pressure of 100-300 atm to form HgBa₂CaCu₂O_{5 + X}Preparing a compound; The HgBaCaCu₂O_{5 + X}Compound and CaCuO_{2 + x}Compounds are mixed at a molecular ratio of 1: 0.5 to 1: 1 and then reacted at a temperature of 820-850C and a mercury vapor pressure of 100-300 atm to form HgBa₂CaCu₂O_{8 + X}Preparing a compound; And HgBaCaCu₂O_{8 + X}Ba-Ca-Cu-O based high-temperature superconductor according to the present invention comprises a step of heat-treating a compound with oxygen at a temperature of 250-300C and a pressure of 1 atm .
