Description

Investigation into gas exchange between BaCuO2±γ composition ceramics and oxidizing atmosphere is conducted using mass spectrometry and low-frequency internal friction methods. It is shown that an anomalous absorption of low-frequency oscillations, detected in the ceramics in question under 150 and 330 deg C can be linked with accumulation of atmospheric moisture by pores. 14 refs.; 5 figs
