Iv. Pulyaeva et al., EFFECT OF SILVER ON THE STABILITY OF YBA2CU3O7-X POWDERS IN A HUMID ATMOSPHERE AND PROPERTIES OF CERAMICS PRODUCED FROM THESE POWDERS, Inorganic materials, 32(7), 1996, pp. 788-794
Electron-probe microanalysis and X-ray photoelectron spectroscopy were
used to study the surface composition of YBa2Cu3O7-x/0.5-15 wt % Ag c
eramics prepared from powders exposed to a humid atmosphere. The super
conducting properties of the composites were found to differ little fr
om those of 123 ceramics.
