摘要:

基于Bi2O3-B2O3-ZnO-SiO2四元体系玻璃,采用ZrO2、TiO2复合掺入,系统研究了不同ZrO2/TiO2摩尔比对玻璃结构、特征温度、膨胀系数及化学稳定性的影响规律。结果表明,少量ZrO2与TiO2复合掺入时,Zr4+会形成Zr—O—Si键,可增强玻璃网络结构,玻璃表现出最佳的耐腐蚀性能。继续增加ZrO2掺量,Zr4+的极化作用会引发Ti4+、B3+、Bi3+配位结构改变,玻璃网络结构被破坏,玻璃的化学稳定性出现下降。当ZrO2完全取代TiO2后,玻璃结构致密性及化学稳定性重新回升。

Abstract:

Based on the Bi2O3-B2O3-ZnO-SiO2 quaternary system glass, the influence laws of different molar ratios of ZrO2/TiO2 incorporation on the glass structure, characteristic temperature, coefficient of expansion and chemical stability were systematically studied by using ZrO2 and TiO2 composite incorporation. The results show that when a small amount of ZrO2 and TiO2 composite doped, Zr4+ will form Zr—O—Si bonds, which can enhance the glass network structure, and the glass will exhibit the best corrosion resistance. However, if the doping amount of ZrO2 is further increased, due to the polarization effect of Zr4+, the coordination structure of Ti4+, B3+, and Bi3+ changes, which disrupts the glass network structure and leads to a decline in the chemical stability of glass. When ZrO2 completely replaces TiO2, the compactness and chemical stability of glass structure is improved again.
