【摘要】用红外光谱测定 YBa₂Cu₃O_7-x 合成过程中碳酸根含量的变化,用燃烧-气相色谱法测定碳含量,以此作为判据,评定合成粉品质,并由此确定 YBa₂Cu₃O_7-x 的合成工艺。更多还原

【Abstract】 The variation of carbonate content in YBa₂ Cu₃ O_7-x supercon-ducting power for calcining process was studied by means of IR absorption me-thod.The carbon content was examined with Combustion-Gas Chromatographmethod.Each of them can be applied to check the quality of YBa₂ Cu₃ O_7-xsuperconducting power and determined suitable process of calcination.更多还原
