用红外光谱测定 YBa_2Cu_3O_(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 YBa_2Cu_3O_(7-x) 的合成工艺。
The change of carbonate content during the synthesis of YBa_2Cu_3O_ (7-x) was measured by infrared spectroscopy and the carbon content was determined by combustion-gas chromatography. The quality of the synthesized powder was evaluated by the determination of YBa_2Cu_3O_ (7-x) The synthesis process.
