| Abstract Scope |
LionGlass is a zinc aluminosilicophosphate (ZASP) glass that eliminates carbonates in its batch composition and has a melting temperature 300-400°C lower than soda-lime glass, effectively reducing carbon emissions by about 65%. Five main LionGlass compositions will be discussed: LG1, KLG1-Ca, KLG1- Mg, and KLG1-CaMg. LG1 is the original composition with Na2O as the significant modifier ion. The KLG1 series is the original composition with Na2O replaced with K2O. Chemical durability, crack resistance, and other mechanical properties have been assessed and compared to soda-lime glass for each composition. Fourier transform infrared spectroscopy (FTIR) will be conducted to better under surface degradation in water. A time-temperature-transform (TTT) diagram predicting vitrification, crystallinity, and cooling rates for phase transformation will be discussed. |
