Abstract

PURPOSE:To obtain a large theoretical oxygen content ratio and a large theoretical density ratio and to secure high values of a critical current and a critical temperature, by blending R2O3 powder, AO powder, and CuO powder in prescribed composition and next mixing a prescribed amount of metal oxide powder for supplying short oxygen to this blended powder and next by putting/sealing the mixed powder into a metallic case to perform a hot hydrostatic press (HIP) process and to form an oxide stuck material and by providing a firing process for the stuck material. CONSTITUTION:R2O3 powder, AO powder, CuO powder, and powder of various metal oxides are prepared as raw material powder. After they are blended and mixed in respective prescribed composition ratios, a case made of Cu is filled with them at a filling rate of 50% and provided with vacuum sealing. This metallic case is housed in an HIP device and provided with HIP processing on prescribed conditions to form an oxide stuck material. Next this oxide stuck material together with the metallic case is provided with a firing process on prescribed conditions in the atmosphere so that the oxide stuck material inside the metallic case is synthesized into ceramics one. In succession, cold swaging processes and cold groove rolling processes are provided respectively at plural times for this stuck material so that a conductor is manufactured. Annealing for distortion removal is also provided for this conductor.
