The Structure and Properties of XZnO-(67-x)SnO-33P₂O₅ Glasses: (IV) Mechanical Properties
The Vickers hardness, Young's modulus, and shear modulus of xZnO-(67-x)SnO-33P2O5 glasses increase with increasing values of x, in agreement with predictions that consider the quantitative structural information regarding coordination numbers of Zn2+ and Sn2+ ions by diffraction methods, and phosphate anion distributions by NMR methods, reported in an earlier study. The compositional dependence of the shear modulus falls into two ranges which correlate with trends in photoelasticity, and the elastic and photoelastic properties are explained considering changes in ion packing ratio and average bond strengths when ZnO replaces SnO.
