| Popis: | The aim of the present work was to study a novel type of borosilicate glass with excellent chemical stability and high ultraviolet transmission. The impact of the content of Al2O3 and B2O3 on the microstructure and ultraviolet transmission of borosilicate glass was studied by Raman, FTIR, SEM and UV–VIS-NIR spectrophotometer. The chemical stability was studied by chemical stability test. The results showed that when the addition of Al2O3 increased, the chemical stability of the glass turned worse. We found that when the addition of B2O3 was 13 wt.%, the erosion degrees of the boron-rich phase of the glass was significantly more serious than other samples. And when the addition of B2O3 was 11 wt.%, it had the best chemical stability. Moreover, the UV transmittance of glass samples gradually decreased with increasing Al2O3 content, and the UV transmittance of glass samples increased first and then decreased with increasing B2O3 content. |
