Notes:
Glasses of composition xM2O:(1-x)SiO2 [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). Phase separation occurs in gel much below Tg, and before it evolves into the structure of melt-quench glass. Thus phase separation is achieved more readily in sintered gels than in the corresponding melt-quench glass.
