Ag concentration in a melt-textured YBa2(Cu1-xAgx)3O7 superconductor with the nominal Ag content x=0.05 was studied by means of wavelength-dispersive spectroscopy. Ag concentration in the secondary phase Y-211 was under WDX detection limit. In the superconducting phase, the Ag content was 4 times above the level corresponding to optimum chemical pinning. Ag atoms clustering was proposed as the reason.
