Abstract

Lead (II) oxide (PbO) has shown high prospect in modifying mechanical, physical, neutron and charge particle interaction properties of geopolymer due to high bonding matrix. In this study, the impact of PbO doping on the microstructure, mechanical strength, neutron and charge particles interaction properties of geopolymer composites was examined. The undoped and doped geopolymer powders were produced and sintered above 1100 °C for 1 h to obtain denser materials. The X-ray diffraction (XRD) analysis showed that the material is rich in cristobalite (C), mullite (M), and lead silicate (P) phases. The EDS analysis of geopolymer gave Si, O, Na and Al with 40.87, 35.37, 6.06 and 17.68% wt respectively as major elements. The Vickers hardness (HV) values for GEO, GEO-10Pb and GEO-20Pb samples were obtained as 595, 647 and 682 HV respectively under 0.5 kg load. The showed that the introduction of 10% and 20% PbO significantly improved the charge particle attenuation, density and Vickers Hardness of the geopolymer while the total fast neutron removal cross-section decreases with increasing lead content.

含 Si、O、Na 和 Al 的新型土工聚合物的合成特性和中子衰减：添加铅的作用

氧化铅（PbO）具有高键合基体，在改变土工聚合物的机械、物理、中子和电荷粒子相互作用性能方面具有很高的应用前景。本研究考察了氧化铅掺杂对土工聚合物复合材料微观结构、机械强度、中子和电荷粒子相互作用性能的影响。制备出未掺杂和掺杂的土工聚合物粉末，并在 1100 °C 以上烧结 1 小时，以获得更致密的材料。X 射线衍射（XRD）分析表明，材料中含有丰富的钙钛矿（C）、莫来石（M）和硅酸铅（P）相。地聚合物的 EDS 分析显示，主要元素为 Si、O、Na 和 Al，重量百分比分别为 40.87%、35.37%、6.06% 和 17.68%。在 0.5 公斤载荷下，GEO、GEO-10Pb 和 GEO-20Pb 样品的维氏硬度（HV）值分别为 595、647 和 682 HV。研究结果表明，10% 和 20% 的氧化铅能显著改善土工聚合物的电荷粒子衰减、密度和维氏硬度，而总的快中子去除截面则随着铅含量的增加而减小。

期刊介绍： The journal Silicon is intended to serve all those involved in studying the role of silicon as an enabling element in materials science. There are no restrictions on disciplinary boundaries provided the focus is on silicon-based materials or adds significantly to the understanding of such materials. Accordingly, such contributions are welcome in the areas of inorganic and organic chemistry, physics, biology, engineering, nanoscience, environmental science, electronics and optoelectronics, and modeling and theory. Relevant silicon-based materials include, but are not limited to, semiconductors, polymers, composites, ceramics, glasses, coatings, resins, composites, small molecules, and thin films.
