Overview

The melt-quenching method has been used to fabricate Na 2 B 4 O 7 - CdO glass system. The XRD diffractometer procedure was used to check the status of these samples. Inter-ionic distance ( R i ) between Cd–Cd, Polaron radius r p , and inter-nuclear distance r i reduced with Cd content due to reducing molar volume. Ionicity I b decreased and covalent glass character increased as CdO in the glass matrix increases. As the CdO contents increase, the values of T g , T c , and T P have been increased. All expected phases are displayed in the XRD patterns. SEM has studied the morphology of the vitreous ceramic. It has been noted that the velocities and elastic modulus of glass-ceramics samples are increased. The structural nature of the developed phase was monitored in spectroscopic FT-IR investigations of the glass-ceramic samples. Mass attenuation Coefficient ( μ/ρ ) increases with CdO-content increase. The Z eff values increase gradually at higher energy because of X-ray K -edges. Hence, the increase in CdO content can be developed the γ -radiation. According to our data, G7 is the best sample for shielding properties.
