Abstract

En 中文

• Mixed alkali (Na + K) tantalum phosphate glasses obtained up to 50mol% Ta2O5. • Mixed Alkali Effect (MAE) in thermal properties, density and electrical properties. • Mixed alkali tantalum phosphate glasses show similar behavior to sodium glasses. • Higher values of mechanical properties for Na and Na–K than K glasses.
