Synthesis Properties and Neutron Attenuation of New Geopolymers Containing Si, O, Na and Al: Role of Pb Addition
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.
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.
