The effect of boron oxide additives in the amount from 0 to 11 mol. % was studied on the melting characteristic of glasses in the SrO–Al2O3–TiO2–ZrO2–B2O3–SiO2 system for use as fillers in dental filling composites in order to reduce
the melting temperature to technologically acceptable values (no more than 1500 ?C) and increase the transparency of the produced granulate. It was found that with an increase in the B2O3 content, the melting temperature can be reduced from 1600 ?C (in glasses without B2O3 additives) to 1480 ?C with a B2O3 content of 11.8 mol. %, while the glass transition temperature decreases from 820 to 743 ?C. Already with a B2O3 content of 6 mol. % at a melting temperature of 1500 ?C, transparent glasses with light transmission of 80 % are produced, promising for the creation of sealing composites.
