摘要： According to this method of manufacturing a superconductor, powder materials of Y.sub.2 O.sub.3, BaCO.sub.3 and CuO are first prepared as raw materials and blended and mixed to the composition Y.sub.1 Ba.sub.2 Cu.sub.3 O.sub.x. The mixed powder thus obtained is compression-molded and thereafter sintered. A sintered body thus obtained shows the Meissner effect under the temperature of liquid nitrogen. This sintered body is pulverized into fine particles. A magnetic field is applied to the fine particles at the temperature of liquid nitrogen, thereby to select only superconductive particles. The selected superconductive particles are compression-molded during application of a magnetic field and then sintered, thereby to obtain a superconductor having high critical current density.
摘要翻译：根据这种制造超导体的方法，首先制备Y2O3，BaCO3和CuO的粉末材料作为原料，并混合并混合到组合物Y1Ba2Cu3Ox中。将由此获得的混合粉末进行压缩模塑，然后烧结。由此获得的烧结体显示在液氮温度下的Meissner效应。将该烧结体粉碎为微粒。在液氮的温度下对微粒施加磁场，仅选择超导性粒子。所选择的超导颗粒在施加磁场期间被压缩模制，然后烧结，从而获得具有高临界电流密度的超导体。
