ABSTRACT

The effect of SiO2, Na2O and CaO on isokom temperatures in soda-lime glass is estimated by comparing calculated isokom temperatures using viscosity model proposed by Lakatos. The isokom temperatures at the viscosity of log η=12.3,10, 6.6 and 1 (Pa·s) are lowered by 6, 7, 10 and 24°C, respectively, by the substitution of SiO2 with Na2O by 1 mol%. Meanwhile, replacing 1 mol% of SiO2 with CaO raises the isokom temperatures by 3~4 and 2°C at the viscosity of logη=12.3 and 10 (Pa·s), respectively, but lowers the temperatures by 1 and 21°C at the viscosity of log η= 6.6 and 1 (Pa·s), respectively.
