Temperature dependence of the mechanical behavior of ZnO-Na2O-P2O5 glasses

Abstract

Abstract In this research, we investigate the mechanical behaviour of zinc sodium phosphate glass system with the various concentration of chromium oxide doped. The glass system was synthesized using the melt quenching technique. The concentration of chromium oxide varying from 0.5% to 2.5%. The ultrasonic wave velocities have been determined as functions of temperature from 273 K and 333 K. The transit time data and density are used to determine all of the mechanical behavior for these glasses, we found that the mechanical behaviour of the glass system decrease as the Cr2O3 content increase, which indicates a weakening of the binding energy in the network.
