【摘要】 采用名义组分为YBa₂Cu₃O_9-x的原料,经过高温陶瓷烧结工艺,制备出高Tc的Y-Ba-Cu-O超导体。测试样品的Tc为91K;X—射线衍射谱分析证明,样品接近单相,其主要相为钙钛矿结构。更多还原

【Abstract】 A high Tc superconductor was prepared by high temperature sintering techningue from the raw materia/s of sintering stoichiometric composition. Tc of the ample is 91k. X—ray diffraction patterns demonstrate that the sample is nearly in single phase and structure of the major phase belongs to the perovskite type.更多还原
