| Abstract Scope |
LionGlass™ is Penn State University’s patent-pending alumino-silicophosphate glass compositional family that offers, for the first time, a viable low carbon-footprint alternative to soda lime silicate glass by (a) lowering the melting temperature by 300-400°C compared to soda lime and (b) eliminating the use of carbonate batch materials. The viscosity curve of LionGlass is shifted downward in temperature compared to soda lime silicate, enabling melting at much lower temperatures. LionGlass also has significantly improved resistance to crack initiation compared to soda lime glass. Other properties, such as thermal expansion coefficient and optical dispersion curve, are comparable to those of traditional soda lime glass. |
