PURPOSE:To separate a superconductive material having a critical temp. >=a specified temp by floating from a mixture contg. the superconductive material to be separated by charging the mixture to a vessel held at a specified temp. and applying a magnetic force to the mixture. CONSTITUTION:For example, liquid N2 is stored in an outside layer section 2 of a glass vessel having a double layered structure, and the inside of the vessel is held at a specified temp. by adjusting a heater 3. A material contg. the superconductive material to be separated is charged to the vessel, and a magnetic force of a magnet 4 is applied to the material. Thus, a superconductive material having a critical temp. >= a specified temp. is floated from said material, and the floated superconductive material is recovered. As a result, the superconductive material having a critical temp. >= a specified temp. is separated, and, for example, superconducting characteristics of products obtd. from the separated superconductive material are improved to higher characteristics than the levels of characteristics of conventional products. Moreover, production processes for several superconductive materials can be utilized effectively. |
