Designing glass with non-dispersive stress-optic response
Galbraith, Justine; Zwanziger, Josef W (Elsevier, 2016-02-01)The dispersion of the stress-optic response of a series of barium and lead phosphate glasses is measured using an ellipsometric method. It is found that the barium glasses display consistently positive dispersion with ... -
Mechanical–Structural Investigation of Ion-Exchanged Lithium Silicate Glass using Micro-Raman Spectroscopy
Calahoo, Courtney; Zwanziger, Josef W; Butler, Ian S (American Chemical Society, 2016-03-21)Micro-Raman spectroscopy was used to determine the structural modifications occurring in a simple ion-exchanged glass. The base lithium silicate composition 30Li2O–70SiO2 was studied as it underwent ion exchange, Li+ ↔ K+, ... -
Nanoindentation Study of the Surface of Ion-Exchanged Lithium Silicate Glass
Calahoo, Courtney; Zhang, Xiaofang; Zwanziger, Josef W (American Chemical Society, 2016-02-25)Variations in mechanical properties (stiffness and hardness) were measured as a function of case depth in ion-exchange glasses using nanoindentation. A simple silicate composition, 30Li2O–70Si2O, was exchanged (Li+ ↔ K+) ...
