为了研究作为制备多孔玻璃起始材料的Na 2 O-B 2 O 3 -SiO 2 -Al 2 O 3 玻璃的微观结构，在21.8 T下检查了 11 B 一维（1D）魔角旋转（MAS）光谱和二维（2D） 11 B- 11 B 同核相关实验结果。我们得出结论，观察到的 11 B 的四个峰中有两个属于硼酸盐 环，我们将其指定为富硼相中的主要成分，通过酸浸去除。
To study microstructure of Na 2 O-B 2 O 3 -SiO 2 -Al 2 O 3 glass, which is a starting material for preparing porous glass, 11 B one-dimensional (1D) magic-angle spinning (MAS) spectra and results of two-dimensional (2D) 11 B- 11 B homonuclear correlation experiment under MAS are examined at 21.8 T. We conclude that two of the four peaks observed for 11 B are assigned to borate rings, which we assign as the main components in the boron-rich phase to be removed by acid leaching.
