本文详细介绍了采用X-射线衍射测定YBa2CuOx中氧含量的实验细节并采用此法测定了六个样品的氧含量.结果表明:分别在空气和氧气中生长的名义成分为123+15wt.%211+0.5wt.%CeO2的样品的氧含量分别为6.63和6.76.经渗氧处理后,氧含量分别增加至6.88和6.94.在名义成分为123+15wt.%211+0.5wt.%pt的样品中也得到类似的结果.本文对采用X-射线衍射测定YBa2,Cu3Ox中氧含量的合理性和测定精度进行了讨论.

Measurement of oxygen contents in YBa2Cu3Ox single crystals by the X-ray diffraction technique has been described in details and six samples have been measured in the present paper.The results showed that the oxygen contents of as-grown YBCO samples with a nominal conposition of 123 +15wt.% 211 + 0.5wt.% CeO2 prepared in air and in flowing oxygen were 6.63 and 6.76,respectively.After oxygen annealing,the oxygen contents increased to 6.88 and 6.94.Similar results were found on samples with a nominal composition of 123 + 15wt.%211 + 0.5wt.%Pt.The rationality of these results and the precision of measurement of oxygen contents by X-ray diffraction have been discussed.
