- Аннотация: The influence of boron oxide additives in amounts 0 to 11 mol.% on the melting properties of glasses in the system SrO–Al2O3–TiO2–ZrO2–B2O3–SiO2 for use as fillers in dental filling composites in order to lower the melting temperature to technologically acceptable values (≤ 1500°C) and to increase the transparency of the produced finely crushed glass. It was found that as the B2O3 content increases, the melting temperature can be lowered from 1600°C (in glass without added B2O3) to 1480°C at B2O3 content 11.8 mol.%, and the glass transition temperature drops from 820 to 743°C. Transparent glasses with light transmission 80%, which are promising for making filling composites, already obtain at 6 mol.% B2O3 with melting temperature 1500°C.
