Abstract :
SiO2-SrO-Na2O glasses containing incremental amounts of yttrium (Y) and/or cerium (Ce), were developed and characterized. Magic angle spinning-nuclear magnetic resonance (MAS-NMR) revealed a primarily Q2/Q3 network for each glass. Additionally, silicon (Si), strontium (Sr), sodium (Na), Y, and Ce ion release studies were completed. The maximum release was found in the control glass (LP-NC) for Si (up to 16210 ppm), Sr (up to 780 ppm), and Na (up to 8016 ppm). No release of Y or Ce was detected in any of the glasses.
