The Preparation of Ceramic YBaCuO System Superconducting wire |
| Abstract |
YBaCuO oxide superconductor-shows superconductive at Liquid Nitrogen temperature-must be preparate wire or thin film form for utility. The wiring is possible with heat treatment after appropriate mixture of polymeric binder and YBaCuO oxide superconductor has fabricated. This study, analyzed the characteristics of fabricated superconductor and extruded wire after application to each of a mixed at different rate in the superconductor and compared with an original pure sample. From the result, we knew that the binder component influences superconducting characteristics. The best condition for superconductivity occurred at a criticla temperature of 86.4K (8:2 rate) and at a critical current density of 100.27A/cmy with a binder packing ratio of about 20~25 percent. |
