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.

Key words: low-melting-point glass, Bi2O3-B2O3-ZnO-SiO2, ZrO2, TiO2, thermal expansion, XPS
