N2 - The local structure of cesium-borosilicate glasses with various Cs2O and B2O3 proportions and constant SiO2 content (50 mol %) is studied with 11B, 29Si, and 133Cs MAS NMR spectroscopy. The portions of three- and four-fold Si atoms are determined, as well as the concentrations of various silicate Qn units. Our experimental data are compared with the predictions of Dell’s model and thermodynamic modeling for sodium–borosilicate analogs of the glasses studied.
