Three ternary lead zinc phosphate glasses with different atomic ratio have been prepared in order to study their structure and mechanical properties. All of them showed high expansion coefficient and weak mechanical properties. Though experimental errors are relatively high, the Young's modulus and modulus of rupture seem to indicate higher values with higher P2O5 content. Surprisingly, the 30P2O5.50PbO.20ZnO (mol%) glass shows a relatively high fatigue susceptibility (n=56.8±2.0), much higher than that of the other two compositions examined and of that of soda-lime-silica glass (n=20).

Abstract
Three ternary lead zinc phosphate glasses with different atomic ratio have been prepared in order to study their structure and mechanical properties. All of them showed high expansion coefficient and weak mechanical properties. Though experimental errors are relatively high, the Young's modulus and modulus of rupture seem to indicate higher values with higher P2O5 content. Surprisingly, the 30P2O5.50PbO.20ZnO (mol%) glass shows a relatively high fatigue susceptibility (n=56.8±2.0), much higher than that of the other two compositions examined and of that of soda-lime-silica glass (n=20).File in questo prodotto:
