WebLow-temperature (350 °C) vitrification in a KNO3-NaNO3-KHSO4-NH4H2PO4 system, containing various additives to improve the chemical durability of the obtained material, was investigated. It was shown that a glass-forming system with 4.2–8.4 wt.% Al nitrate admixtures could form stable and transparent glasses, whereas the addition of H3BO3 … WebJul 27, 2024 · The presence of TiO 2 increased the Tg from 542 to 575 °C and Tc from 884 to 898 °C. The significant effect of TiO 2 in increasing the Tg and Tc temperatures could be explained by the fact that the number of non-bridging oxygen decreased with the increase in the TiO 2 content in the glass.
