Mechanical and Structural Properties of Zinc - Sodium - Phosphate Glasses Doped with Cu_2O

摘要

Ternary Zinc-Sodium-Phosphate glasses doped with copper of the composition 40ZnO-(20-x) Na_2O-40P_2O_5-xCu_2O where x =0, 2, 4, 6, 8 mol % were prepared by the tradition quenching method. The effect of Cu ions on density, molar volume and microhardness has been investigated. FTIR was measured in the range (400-1600) cm~(-1) to investigate the effect of Cu ion on the structure of the studied glass. Longitudinal and shear velocities were measured for the studied glass using pulse echo technique. Elastic properties such as longitudinal modulus, shear modulus, bulk modulus, and Young's modulus, Poisson's ratio) and some physical parameters such as softening temperature, hardness, Debye temperature have been calculated. The ultrasonic results and the other measured parameters indicate the Cu ion increase the cross-link density by the formation of P-O-Cu. All the measurements are measured at room temperature.
