Abstract
In this study, BaO-ZnO-TiO2 SiO2 was used as the research system, and IR, XRD and DTA analysis were used to study the structure, thermal behavior, crystallization phenomenon and chemical stability of the glass when different proportions of ZnO gradually replaced BaO in this system. The results indicate that replacing BaO with ZnO does not change the amorphous structure of the glass, and the density of the glass increases with the increase of ZnO content. With the increase of ZnO content in glass, the tendency of devitrification increases during cooling, indicating an increased tendency for surface crystallization of glass. The glass with high ZnO content has the highest density and refractive index, and has the best water resistance. However, at this time, the glass is easier to crystallize after heat treatment.
