摘要：

Thc local geometric and electronic order around aluminium atoms in calcium aluminosilicate glasses is comparatively investigated by X-ray absorption (XAS) and by nuclear magnetic resonance (MAS NMR). The Al absorption spectra contain features which can be decomposed into two subpeaks, the relative contribution of the subpeaks appears to be related to the silicon/aluminium ratio in the glass. MAS NMR data analysis of the same samples clearly shows differences in site structures. It is of great interest to compare the results of both techniques in order to describe a reliable picture of Al surroundings related to a number of physical properties of calcium aluminosilicate glasses.
