摘要：

The isotopic method has been used to measure the concentration of hydrogen in as-prepared (Ba, Sr)CeO3 and (Ca, Sr, Ba)TiO3 samples. Hydrogen concentrations in the range 0.007 to 0.04 of H per formula unit have been detected for undoped samples, and even more for doped specimens. The influence of cation composition, dopant number density, and preparation method is analyzed. Thermal desorption studies and comparison of hydrogen and oxygen mobilities have been utilized to analyze the state of the dissolved hydrogen. © 1992.
