Abstract:

To investigate the effect of the lanthanides and non-lanthanides elements on the thermal stability and structure of ZnO-B2O3-SiO2 glass, the crystallization behavior, thermal stability and structural changes of ZnO-B2O3-SiO2 glass doped with La2O3 and Y2O3 were characterized by the differential scanning calorimetry (DSC) and Fourier Transform Infrared spectroscope (FTIR). The results showed that when the La2O3 and Y2O3 additions are more than 8mol% and 6mol%, respectively, the 60ZnO-30B2O3-10SiO2 glass system begins to crystallize. When La2O3 and Y2O3 additions are 4mol% and 2mol%, respectively, this glass is of the best thermal stability. According to the structure research, the network linking performance of this kind of glass can be improved by a small amount addition of rare earth oxide. In contrast, the network linking performance of this kind of glass can be decreased by rare earth oxide’s addition exceeding a certain threshold value.
