Effect of Droplet Phase Separation on Mechanical Properties of Calcium Aluminosilicate Glasses

Phase separated glass could have the ability to improve mechanical properties while maintaining optical transparency. In this study, we present the results of phase separated calcium aluminosilicate glass. Our results show a negative correlation between the Poisson’s ratio and crack resistance as a function of heat treatment temperature. This suggests that the involvement and formation of non-bridging oxygens in the matrix phase is the underlying means for the observed phenomenon. Densification may also play role, although additional work is required to test this hypothesis.
