Solubility of water in molten glass
JSGT 1957 V41T304-T317
The solubility of water in molten silicate glasses has been studied in an apparatus which removes water by bubbling a dried gas through the melts. The amount of water which can be extracted from a glass, saturated with water vapour at a partial pressure of 1 atm, is of the order of 1 cm3 of water vapour at N.T.P. per 1 g of glass when the temperature is 1400°C. The temperature coefficient of solubility in a series of disilicate glasses was found to be related to the field strength of the cations in those glasses. When the cationic field strength is high, the solubility increases with increasing temperature but it decreases when the field strength is low
