摘要: Nuclear magnetic resonance spectroscopy (NMR) using magic-angle sample-spinning (MASS) methods is a relatively new technique for examining the structural environment of atoms in both crystalline and amorphous solids. In this paper we will briefly review theory MASS NMR some data silicates silicate glasses. We demonstrate that various nuclides (primarily silicon-29, aluminum-27, oxygen-17) can 1) determine range Si-O-Si bond angles SiO2 glass, 2) presence or absence Al(4) Al(6) aluminosilicate glasses, 3) estimate polymerization states SiO4 tetrahedra 4) different types oxygens CaO-MgO-SiO2 Pb2SiO4 5) examine similarities differences between glass polymorphs. Using available data, hope to illustrate potential application limitations examing
