A glass system was manufactured by substituting CeO2 for ZnO in concentrations ranging from 0 to 1 mol% in the glass matrix. The mechanical parameters and elastic characteristics of the glass system were evaluated using the Makishima-Mackenzie model and sound wave velocity measurements, respectively. The results showed that increasing CeO2 doping ratio enhanced the density, sound velocities, elastic properties, and microhardness of the glass. The replacement of ZnO with CeO2 improved the shielding capacity of the glass.
The glass system 75B2O3 -4.5ZnF2 - 0.5 Er2O3-(20 -x) ZnO-x CeO2, x = (0 <= x <= 1 mol. %) was manufactured using a melt quenching process, with CeO2 substituted for ZnO in the glass matrix in concentrations ranging from 0 to 1 mol %. The Makishima-Mackenzie model and sound wave velocity measurements were used to evaluate the mechanical parameters and elastic character-istics of the examined glass system, respectively. The results showed that increasing CeO2 doping ratio from 0 to 1 mol% increased density, sound velocities, elastic properties, and microhardness from 5.80 to 9.01 GPa. Phy-X/PSD software was employed to assess the effect of replacing ZnO with CeO2 on shielding capacity. The obtained results revealed that replacing ZnO with CeO2 enhances shielding characteristics and the manufactured glass may be useful in shielding applications.
