摘要
利用拉曼光谱研究了具有不同 Cs/Na 比率的两种成分的硼硅玻璃和玻璃陶瓷材料的结构。这些材料是以两种不同的模式合成的。研究了铯在玻璃中的阴离子环境以及结晶相形成过程中网络结构的重新排列。通过玻璃陶瓷样品的 X 射线衍射图样，可以确定唯一的结晶相 CsBSi2O6，但其结构尚未明确确定。所研究成分的玻璃陶瓷可用于固定铯，方法是将铯纳入 CsBSi2O6 成分的结晶相中，而钠则保留在玻璃基质中。这些研究表明，结晶相的组成并不取决于碱阳离子的初始比例，而有序相和无定形相的比例则受熔体冷却过程动力学的控制。
Crystallization of Na- and Cs-Bearing Borosilicate Melts: Results of Raman Spectroscopy
The structure of borosilicate glass and glass-ceramic materials of two compositions with different Cs/Na ratios was studied using Raman spectroscopy. The materials were synthesized in two different modes. The anionic environment of cesium in the glass and the structural rearrangements of the network during the formation of crystalline phases have been studied. X-ray diffraction patterns of glass-ceramic samples made it possible to determine the only crystalline phase CsBSi2O6, the structure of which was not clearly determined. The glass-ceramics of the studied composition can be used to immobilize cesium by incorporating it into the crystalline phases of the CsBSi2O6 composition, while sodium is retained in the glassy matrix. These studies showed that the composition of the crystalline phase does not depend on the initial ratio of alkali cations, while the proportion of the ordered and amorphous phases is controlled by the kinetics of the melt cooling process.
