Phase Separation And Structural Differences Between Alkali Silicate Glasses Parepared By The Sol-Gel And Melt-Quench Method

Glasses of the composition xM20:(1-x)Si02[M=Na,Li] with x=0.15 and 0.2 have been prepared both by the melt-quench and the sol-gel methods. X-ray photoelectron spectroscopy shows that with increasing sintering temperature the structure of gels approaches that of the melt-quench glass but does not become identical even on heating above the glass transition temperature (Tg).
