Title: Manufacture of oxide superconductor
Inventor: SADAKATA NOBUYUKI
IPC: C01G1/00
Filed: 1987-07-23
Abstract: PURPOSE:To improve the thermal stability in the cooling process so as to eliminate a partial peeling-off at the interface between an oxide superconductor and a metal pipe and to speed up the cooling, by maintaining the filled pipe at a high pressure condition at least either in the heat treatment or after the heat treatment. CONSTITUTION:After crushing a material powder sufficiently to make the particle diameters uniform, it is filled in a metal pipe consisting of a precious metal such as silver or a silver alloy to form a filled pipe, to which a diameter contraction process is given to obtain a long linear material of a desired diameter. The linear material is heated and sintered at 850 to 1300 deg.C under a pressure of several thousands kg/cm<2> for 1 to 100 hours, and a heat treatment to cool gradually after the heating is applied to grow up a superconductive substance continuously inside the metal pipe to obtain a superconductor. Since the heat treatment is executed under a high pressure in this case, the metal pipe is pressed to attach to the sintered body side owing to the high pressure, even though a heating contraction is generated, and no gap is generated between the metal pipe and the formation. Consequently, the superconductor can be cooled securely, and a quenching phenomenon can be eliminated rapidly.
