| titleOfInvention | Method for producing RE123-based bulk oxide superconductor |
| abstract | PROBLEM TO BE SOLVED: To melt and solidify a RE123-based oxide superconducting bulk material which can simplify a manufacturing process and stably grow a target large bulk material having good orientation. The present invention provides a production method by the method. SOLUTION: After heating and raising the temperature of a bulk body forming material to decompose and melt it, the temperature is lowered, and a seed crystal is brought into contact with the surface in a temperature range lower than the decomposition temperature as shown in FIG. After seeding, crystal growth is performed at a crystal growth temperature. In this case, it is preferable to use a crystal having the same chemical composition as the “bulk to be produced” as a seed crystal, and to preheat the crystal before seeding. As a seeding method, the seed crystal is supported by a wire of “a metal or an alloy having a melting point corresponding to the seeding temperature” and brought close to the seeding surface, A suitable method is to drop the seed crystal onto the seeding surface by melting the wire. |
