Nature of Incorporated Water in Hydrated Silicate Glasses

Silicate glasses show a wide range of responses to exposure to water or steam at high temperatures and pressure. The response patterns and the factors determining these patterns are discussed. The manner in which water is incorporated in the silicate glasses is elucidated by a study of the near infrared spectra and differential thermogravimetric analysis of hydrated glasses. Factors affecting relative amounts of tightly bonded and loosely bonded water are discussed.
