| 摘 要： | 采用激光拉曼光谱和富里叶变换红外光谱分析技术研究了CaO-Al2O3-SiO2铝硅酸盐熔体化学组成对熔体结构的影响。指出SiO2含量的增加，将使熔体网络结构由层链状为主向架层状过渡，Al2O3和CaO含量的增加，造成部分Al^3 和Ca^2 作为网络修饰子起解聚作用。

| Abstract: | In this work,the structures of tribasic aluminosilicate melts and the effects of melt composition on structures were studied by Laser Raman spectroscopy and IR spectroscopic method,and it is concluded that the structures of the aluminosilicate melts are significant influenced by the melt composition. With increasing percentage of SiO2 ,the melt network structures changes from sheet and chain to frame and sheet. An increase in percentage of A12O3 and CaO led to depolymerization of metis by part of A13+ and surplus Ca2+ which act as network-modifying cation. |
