Abstract
The techniques of melt-quenching were used to manufacture 53B(2)O(3)-2NaF-27PbO-(20 -x)BaO-x La2O3 (0 <= x >= 15) glass system. To check the status of these samples, the XRD diffractometer procedure was used. The molar volume of the glass system is decreased while density is increased. The current glass sample's mechanical properties depend on the glass structure. Ultrasonic velocity and elastic modulus (experimental and theoretical) of glass samples were observed to be increased. FT-IR analysis shows that with the increase of La2O3 increases the changes of BO3 to BO4 and increases the degree of glass connectivity and the structural units of (BO3/2 F)(-) tetrahedra are formed. It has been noted that the MAC values of glass samples are decreased to 1 meV, apart from a small increase at 0.1 meV. At low energy, this significant decline and small peak are directly linked to the current photoelectric effect. The sample with the highest La2O3 content is owned the MAC's greatest values. It has been noted that the (HVL) and (TVL) increase with the increase in the photon energy and La2O3 content rendering to the achieved results. It has been noted that the Zeff has the largest values at lower energy and at lowering concentration of La2O3 content. It has been noted that EABFs and EBFs have originally lower values at low energy levels, because the photoelectric effect dominates and BaO is replaced by La2O3.
