Abstract:

We have prepared perovskite-like Ba2In2-x W (x) O5 + 3x/2 (0 a parts per thousand currency sign x a parts per thousand currency sign 0.67) solid solutions containing oxygen vacancies, whose concentration decreases with increasing x. Thermogravimetry data indicate reversible interaction of the solid solutions with water vapor in the temperature range 250-450A degrees C, which leads to the formation of proton defects in the structure of the oxides. The nature of the forming H+-containing species has been identified by IR spectroscopy. Raman spectroscopy has been used to determine the positions of the In3+ and W6+ ions in the structure of the solid solutions and assess the effect of hydration on their local environment and that of the composition of the solid solutions on the degree of hydration.
