Description

The influence of silver on the properties of the YBa2Cu3O7-x/Ag powder exposed to moist atmosphere has been studied. The powder containing 15% mass of silver has been found to absorb water much weaker in the atmosphere with relative humidity of 86% than it does the powder of the conventional composition in similar conditions. When analyzing ceramic samples produced by hot pressing we revealed the introduction of silver into the powder and its moistening to contribute the ceramics densification. It is demonstrated that ceramics made of moistened powder of the 1-2-3/Ag composition sacrifices no superconducting properties. 25 refs., 5 figs., 3 tabs
