TEM,DTA, X-ray diffraction results reveal that there is a strong tendency of phaseseparation in the ZnO-Al_2O_3-SiO_2 (ZAS) glass.β-quartz solid solution would be crystal-lized out as metastable initial crystalline phase when the degree of phase separation ofthe original glass is low.Whereas β-quartz solid solution and β-willemite solid solutionwould both be crystallized out when the degree of phase separation is more perfect.Itwas found that the degree of phase separation not only determines the initial crystallinephase,...

透射电镜、差热分析以及X射线衍射分析的研究结果表明,ZnO-Al_2O_3-SiO_2(ZAS)玻璃具有较强的分相倾向。当原始玻璃的分相程度较低时,在晶化时析出的亚稳初晶相为β石英固溶体;若分相程度较完善,则析出的初晶相为β石英固溶体和β硅锌矿固溶体。同时从实验结果得出:分相不仅会改变初晶相类型,而且会加速ZAS玻璃的析晶。

The results clearly indicate that the employed variables-Fe2O3 concentrations (0-10 wt%) and crystallization time (0-100 hours) are directly responsible for the variation in the valence, coordination states, and the symmetry of the electrical environment of iron in the dominant crystallized β-quartz solid solution.
