Amassed borophosphate lithium molybdate samples were synthesized by the melting classical technique. To check the conditions of these synthesized glasses, the X-ray diffractometer technique was applied. The density value of these samples was increased as well as the molar volume decreased. The mechanical characteristics were linked with Fourier-transform infrared spectrum results. The addition of MoO3 increases the polymerization degree and changes the basic boring units from BO3 to BO4, increases the polymerization degree of phosphate network and changes the negative non-bridging oxygen to positive charges. Ultrasonic velocities and elastic modulus (experimental and theoretical) are increased. This behaviour is correlated to the substitution of Li–O with Mo–O linkages. Mass attenuation coefficient of the prepared samples decreased with the energy increase and with the addition of MoO3. With the increase in photon energy and MoO3 half value layer, the tenth value layer and the mean free path values increase. Hence, the increase of MoO3 leads to a better attenuation of gamma radiation. Therefore, the glass under investigation had superior characteristics for radiation protection applications.

B2O3–P2O5–Li2O–MoO3 玻璃的机械和辐射屏蔽性能

通过熔融经典技术合成了积累的硼磷酸盐钼酸锂样品。为了检查这些合成玻璃的状况，应用了 X 射线衍射仪技术。这些样品的密度值增加以及摩尔体积减少。机械特性与傅立叶变换红外光谱结果相关联。MoO3的加入提高了聚合度，使基本孔单元由BO3变为BO4，增加了磷酸盐网络的聚合度，使负非桥连氧变为正电荷。超声波速度和弹性模量（实验和理论）增加。这种行为与用 Mo-O 键取代 Li-O 相关。所制备样品的质量衰减系数随着能量的增加和MoO3的加入而降低。随着光子能量和MoO3半值层的增加，第十值层和平均自由程值增加。因此，MoO3 的增加导致伽马辐射更好的衰减。因此，所研究的玻璃在辐射防护应用方面具有优越的特性。
