Role of MoO3 /ZnO substitutions on radiation shielding and mechanical characteristics of lead silicate glasses

In the composition range of x= 0-5 mol%, glasses in the system 60SiO2-35Pb3O4-(5 − 𝑥𝑥) ZnO-xMoO3 have been investigated. An amorphous network structure characterizes the glasses. The density values for the LZSM glasses scaled between 5.91 g/cm³ for Mo0 and 6.249 g/cm³ for Mo5. The ultrasonic technique indicates that the shear and longitudinal speeds (VT & VL) increase linearly as the amount of MoO3 substituted for ZnO in the fabricated glasses increases. The elastic moduli were calculated and found to be increased with an increase in both ultrasonic velocities and density of the glass, which suggests a correlation between these parameters in the fabricated glasses. The radiation attenuation capacity with the addition of MoO3 increased systematically, which indicates the role of MoO3 in modifying the glass composition and enhances its ability to attenuate against harmful radiation. Mo5 establishes excellent protective resources compared to other substances, so Mo5 develops a favorable selection for building radiation absorption blocks. Such blocks show an acute character in protecting both nature and a person's health versus the dangerous impacts of radiation exposure.
