Study of metal distributions in YBa2Cu3O7-x/Ag2O composites

Abstract

The micro proton-induced x-ray emission technique has been used to study the elemental distribution profiles of high- composites on varying the content. Measurements revealed that Ag agglomeration starts to appear in samples with , becoming prominent at 50 wt%. These results are further supported by x-ray diffraction (XRD) measurements performed on the same samples. The XRD results identified a crystalline Ag phase to be present in all of the samples (7-50 wt% ), a crystalline phase in the 25 and 50 wt% samples and no evidence for Ag replacing Cu or orthogonal-to-tetragonal transformation
