PURPOSE:To produce a high-temperature superconducting ceramic electromagnet in which a wire rod is insulated and fixed with efficiency and reliability, by forming a high-temperature superconducting ceramic wire rod in a coil-shape, and by employing an insulating ceramics as the filler by which the resulted coil is fixed in a bobbin, and by sintering both the wire rod and the ceramic simultaneously. CONSTITUTION:An un-sintered high temperature superconducting wire rod 3 is formed in a cylindrical spiral-shaped coil on a ceramic insulating member 2 which is deposited on the surface of a bobbin 1 using a flame spraying technique. Subsequently, starting powder of an insulating ceramic 4 is filled in both the section between the turns and the necessary section. Next, the starting powder of the ceramic 4 is heated from the peripheral section thereof with being pressurized so that both the high temperature superconducting wire rod 3 and the insulating ceramic 4 are sintered simultaneously. |
