Abstract

Structures of glasses containing (20-30) mol% CeO2-(16-23) mol% Al2O3-(47-64) mol% SiO2 prepared at 1550°C for 3 h in an atmosphere of N2 have been investigated via the analyses of FT-IR and 27Al MAS-NMR spectroscopy. Results show that cerium ions act primarily as the glass modifiers. The number of NBO/T on average in the structures of CAS glasses increases with increasing ceria content. The aluminum ions in the structures of CAS glasses exist in both Al(6) and Al(4) coordination, and the fraction of Al(6) is more than Al(4).
