Mixed-Alkali Effect on Thermal Property and Elastic Behavior in Borosilicate Glasses

We investigated the mixed alkali effect on the thermal properties and elastic response to temperature in the borosilicate glasses system with the composition of 70.65SiO 2 ·21.09B 2 O 3 ·1.88Al 2 O 3 ·(6.3 8− x )Li 2 O· x Na 2 O glasses, where x = 0.00, 1.595, 3.19, 4.785, and 6.38. Except for the e...

Description
Summary:We investigated the mixed alkali effect on the thermal properties and elastic response to temperature in the borosilicate glasses system with the composition of 70.65SiO 2 ·21.09B 2 O 3 ·1.88Al 2 O 3 ·(6.3 8− x )Li 2 O· x Na 2 O glasses, where x = 0.00, 1.595, 3.19, 4.785, and 6.38. Except for the expected positive and negative deviations from linearity for the coefficients of thermal expansion, room temperature E and G , we observed a new mixed alkali effect on the response of elastic moduli to temperature. Fourier transform infrared spectra were obtained to elucidate the possible structural origin of the mixed alkali effects. This work provides a valuable insight into the structural and mechanical properties of mixed-alkali borosilicate glasses.
