View article: Effect of calcium and potassium oxide addition on the viscosity and fragility of a calcium aluminosilicate melt
Effect of calcium and potassium oxide addition on the viscosity and fragility of a calcium aluminosilicate melt Open
Fragility is commonly quantified as the magnitude of change in viscosity at a temperature close to the glass transition temperature ( T g ). It is a critical characteristic of melts used in scientific and industrial applications. The fragi…
