摘要

本文研究了BaO包合物对77Li2B4O7-11SiO2 -(12-x)MgO-xBaO（0≤x≤12 mol%）的结构、力学和γ射线屏蔽的影响。FT-IR证实BaO的加入增加了BO4，降低了BO3。LBSMBa0的摩尔密度从2.89增加到3.83，而LBSMBa12的摩尔体积从49.02下降到40.53。两种速度均有所增加，LBSMBa0的VLm/s从4634增加到4890，LBSMBa12的VT m/s从2165增加到2318。提高了LBSMBa玻璃的弹性模量。物理-x代码证实了BaO对γ屏蔽效率的积极影响。LBSMBa玻璃的MAC值有如下趋势：LBSMBa12>；LBSMBa9祝辞LBSMBa3祝辞LBSMBa1.5祝辞LBSMBa0。因此，LBSMBa12样品可以比其他样品更多地用于屏蔽应用。

Studying structural, mechanical, and radiation shielding properties for BaO–Li2B4O7–SiO2–MgO glasses

This article investigates the impact of the inclusion of BaO on the structural, mechanical, and γ-ray shielding of the glass composition 77Li₂B₄O₇–11SiO₂-(12-x)MgO-xBaO (0 ≤ x ≤12 mol%). FT-IR confirms that the inclusion of BaO increases BO₄ and decreases BO₃. The density increased from 2.89 for LBSMBa0 to 3.83 for LBSMBa12, while the molar volume decreased from 49.02 for LBSMBa0 to 40.53 for LBSMBa12. Both velocities were increased, (V_Lm/s) increased from 4634 for LBSMBa0 to 4890 for LBSMBa12, while (V_T m/s) increased from 2165 for LBSMBa0 to 2318 for LBSMBa12. The elastic modulus values of LBSMBa glasses were increased. Phy-x code confirms the positive impacts of BaO on the

shielding efficiency. The MAC values of LBSMBa glasses have the trend: LBSMBa12> LBSMBa9 > LBSMBa3 > LBSMBa1.5 > LBSMBa0. Thus, the LBSMBa12 sample can be used in shielding applications more than the other samples.

期刊介绍： In 1985, the Journal of Science was founded as a platform for publishing national and international research papers across various disciplines, including natural sciences, technology, social sciences, and humanities. Over the years, the journal has experienced remarkable growth in terms of quality, size, and scope. Today, it encompasses a diverse range of publications dedicated to academic research. Considering the rapid expansion of materials science, we are pleased to introduce the Journal of Science: Advanced Materials and Devices. This new addition to our journal series offers researchers an exciting opportunity to publish their work on all aspects of materials science and technology within the esteemed Journal of Science. With this development, we aim to revolutionize the way research in materials science is expressed and organized, further strengthening our commitment to promoting outstanding research across various scientific and technological fields.
