利用同步辐射的AlK边X射线吸收近进结构（XANES）谱研究了刚玉和铝硅酸盐矿物（蓝晶石，红柱石，夕线石和钠长石）中Al的配位与局部结构，证明该方法可以作为新的结构探针研究结构未知体系中Al的配位与局部结构。例如，Al的K边XANES谱证明在室温压条件，钠长石玻璃中的Al保持为四面体配位（AlIV），局部结构与钠长石晶体中的Al相似；尽管硬玉晶体中的Al为八面体配位，但硬玉玻璃中的Al变为四面体配位（AlIV）。而在相同的高温压条件（4．4GPa，1575C）下制备的硬玉-钠长石玻璃系列中，压力引起四面体配位的Al变成五次（Alv）和六次配位（AlVl），且五次和六次配位Al的比例随玻璃中硬玉含量的增加而增大。
The coordination and local structure of Al in corundum and aluminosilicate minerals (kyanite, andalusite, sillimanite and albite) were investigated by X-ray absorption near structure (XANES) spectra of synchrotron radiation This method can be used as a new structural probe to study the coordination and local structure of Al in the unknown structure system. For example, the K-side XANES spectra of Al demonstrate that at ambient temperature, Al remains in the albite glass as a tetrahedral coordination (AlIV) with local structure similar to Al in albite crystals; although Al in the jadeite crystals is Octahedral coordination, but the jade glass of Al into tetrahedral coordination (AlIV). In the series of jadeite-albite glasses prepared under the same high temperature and pressure conditions (4.4GPa, 1575C), the pressure causes tetrahedrally coordinated Al to become Alv and AlVl, And the proportions of the fifth and sixth coordination Al increase with the increase of the content of hard jadeite in the glass.
