Paper Abstract

Dried sol-gel silicate materials containing metal ions (2Th02-2M20-96Si02; where M = Na, K, or Cs) were ion-exchanged at 25 °C in selected regions using microelectronic masking methods and ionic solutions. After heat densification, the compositions and properties of the exchanged and unexchanged regions of the gel were investigated by microscopy, SEM-EDAX, and micro- Raman spectroscopy. Comparison of the spectra with those of melt-quench glasses of the same stoichiometries, exchanged identically, shows the effectiveness of the gel exchange.
