The properties of zinc sodium phosphate glass system with the various concentration of chromium oxide doped

Abstract

In this research, we investigate the properties 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 chromium oxide presence makes the range value was smaller for the density and the molar volume thus making its the structure of this glass system more stable. We perform the Vicker Hardness test using 980 mNewton pressure. The test results show the concentration of chromium oxide effect to the hardness scale of glass system. We also perform FTIR test for knowing the relationship between the wavenumber and percentage of transmittance.
