氧化物熔体和玻璃的结构和动力学：从多核高温NMR看
Structure and dynamics of Oxide Melts and Glasses : a view from multinuclear and high temperature NMR
摘要：
固态核磁共振（NMR）实验可以表征氧化物玻璃和熔体的局部结构和动力学。由于新实验的发展，现在不仅可以证明玻璃网络形成者的配位状态的细节，而且还可以表征延伸到几个化学键上的多原子分子图案的性质。我们目前的结果涉及31 P homogeneous实验，允许多达三个磷酸盐单元和27 Al/17 O heterogeneous，允许证明3个氧桥在铝酸盐玻璃和高温熔体的结构的重新讨论组的描述。
英文摘要：
Solid State Nuclear Magnetic Resonance (NMR) experiments allow characterizing the local structure and dynamics of oxide glasses and melts. Thanks to the development of new experiments, it now becomes possible to evidence not only the details of the coordination state of the network formers of glasses but also to characterize the nature of polyatomic molecular motifs extending over several chemical bonds. We present results involving 31P homonuclear experiments that allow description of groups of up to three phosphate units and 27Al/17O heteronuclear that allows evidencing μ3 oxygen bridges in aluminate glasses and rediscussion of the structure of high temperature melts.
