To study microstructure of Na2O–B2O3–SiO2–Al2O3 glass, which is a starting material for preparing porous glass, 11B one-dimensional (1D) magic-angle spinning (MAS) spectra and results of two-dimensional (2D) 11B–11B homonuclear correlation experiment under MAS are examined at 21.8 T. We conclude that two of the four peaks observed for 11B are assigned to borate rings, which we assign as the main components in the boron-rich phase to be removed by acid leaching.
