Abstract
The kinetics of ion exchange of Na+ far Li+ in an alkaline-silicate gl ass in a salt melt containing Li+ mere studied in the temperature rang e from 180 to 250 degrees C. The results obtained (the reaction front rate and the fragment size of the fractured product) were compared wit h the predictions of the previously suggested quantitative model. Theo retical predictions differ from the experimental data by less than 30% .
