The NMR interactions of crystalline phases in the system Na2O-ZrO2-SiO2 have been studied by a combination of static and magic angle spinning NMR methods for the first time. A full multinuclear (17O, 23Na, 29Si and 91Zr) approach has been employed that allows the phases to be clearly identified. NMR interactions such as 29Si isotropic chemical shift correlate with the known structural units present. For 23Na the the different sites can often be distinguished on the basis of differing quadrupolar interactions.
首次通过静态和魔角旋转核磁共振方法相结合的方式研究了Na2O-ZrO2-SiO2体系中晶相的核磁共振相互作用。采用了全面的多核(17O、23Na、29Si和91Zr)方法,使得各相能够被清晰识别。诸如29Si各向同性化学位移等核磁共振相互作用与存在的已知结构单元相关。对于23Na,不同的位点通常可以根据不同的四极相互作用来区分。
