"The effect of dissolved water on borate glasses containing 4-20 mol % Ag2O was investigated. Water was dissolved in the glasses by bubbling with a carrier gas (oxygen) containing different partial pressures of water vapor. A minimum in water solubility was found at 11 mol % Ag2O. Water contents in excess of 0.5 mol % H2O did not have a great effect on the transition temperature or the dilatometric softening point. Below 15 mol % Ag2O, the water content had no effect on the thermal expansion coefficients. Beyond 15 mol % Ag2O, the thermal expansion coefficients remain nearly constant for the wet glasses, but show a slight increase for the dry glasses. The water content was not observed to significantly affect the UV or visible spectra before or after x-ray irradiation. Differences in the location of the UV absorption edge and the minimum in the water solubility curve, when compared to alkali borate glasses, is attributed to electronic differences between silver and alkali ions"--Abstract, page ii.
