摘要/Abstract

摘要： 基于K₂O-B₂O₃-SiO₂三元体系玻璃,在固定玻璃组成参数R值的基础上,设计了不同玻璃组成参数K值含Ag碱硼硅酸盐玻璃。采用熔融法制备了基础玻璃,在析晶温度范围内经过一步法热处理,所有样品内部都析出了球形的AgCl晶粒。研究表明,玻璃组成参数K值对含Ag碱硼硅酸盐玻璃体内AgCl晶粒的析出产生了明显影响。对于设计制备的弱分相体系玻璃,玻璃组成参数K值的改变可以影响玻璃网络的聚合度,但玻璃的分相并不是影响玻璃析晶的主要因素。通过玻璃结构分析,玻璃组成参数K值的改变能够对ZrO₂在玻璃网络中的存在状态产生影响,进而降低ZrO₂在玻璃网络中的溶解度,增加了基础玻璃中的成核位点,从而对含Ag碱硼硅酸盐玻璃的AgCl析晶行为产生重要影响。

Abstract: Based on the K₂O-B₂O₃-SiO₂ ternary system glass, different glass composition parameters K values of Ag-doped alkali borosilicate glass were designed based on a fixed glass composition parameter R values. The base glass was prepared by melting method, and a one-step heat treatment within the crystallization temperature range resulted in the precipitation of spherical AgCl crystallites in all samples. The study indicates that the different glass composition parameters K values have a significant impact on the precipitation of AgCl crystallites within the Ag-doped alkali borosilicate glass. For the designed weak phase separation system glass, the variation of the glass composition parameter K values can affect the network polymerization of the glass, but the phase separation of the glass is not the main factor affecting the glass crystallization. Through glass structure analysis, the change in the glass composition parameter K values can affect the existence state of ZrO₂ in the glass network, thereby reducing the solubility of ZrO₂ in the glass network, increasing the nucleation sites in the base glass, and thus exerting a significant influence on the AgCl crystallization behavior in the Ag-doped alkali borosilicate glasses.
