Abstract
The conventional acid-base concepts in glass are discussed and a new hypothesis to define basicity of a borate or a silicate glass has been proposed. The role of non-bridging oxygen in glass is compared with that of hydroxyl ion in aqueous solutions. Chromium (VI), Vanadium (V), Uranium (VI), Cobalt (II), and Nickel (II) are found to exist in glass in acidic and basic forms with very different optical absorption; these ions can successfully be used as “colour indicators” to study the acid-base character of a glass. The influence of acid-base property on oxidation-reduction equilibrium of transition metal ions in glass is discussed.Keywords
