Enthalpies of Mixing of Two Alkali Glasses and Glasses Containing Alkali and Alkaline-Earth Cations

摘要

The enthalpy of mixing of silicate glasses containing Na, K, and Ba cations is estimated using differential thermal analysis. It is shown that the interaction of sodium silicate and potassium silicate glasses with barium silicate glass is an endothermic process, whereas the interaction of sodium silicate glass with potassium silicate glass is an exothermic process.
