With revolutionary advancements in technology, it is inevitable to not to develop the quality of concrete as it now a basic requirement for infrastructure. The objective of this review is to highlight the main aspects of Heavy Weight Concrete which covers the general concept of radiation physics being used in HWC, advancements in HWC technology, applications of HWC, cost optimization of HWC and future challenges. Recent researches have shown the requisite for Heavy Weight Concrete as it can efficiently absorb attenuate the radiation thus it is being used in nuclear facilities, medical facilities and now it is even being used in modern warfare. According to the past studies it is found that HWC can be used for shielding from high level radiations such as alpha-rays, beta-rays, X-rays and gamma-rays. Some of the rays propagated form radioactive material can be halted easily but some rays possess ultra-penetration ability and can penetrate through living being near them which results in destructive ionization of biological cells of a living being. This comprehensive review reaches out to the several critical areas such as future uses of HWC, cost optimization in HWC can be done by adding industrial residue of steel, glass, plastic fibers and other natural materials that can be used in HWC and increasing atomic mass for producing high quality radiation attenuation concrete.

Herein, the crystal structure, surface morphology, and magnetic and thermal properties of the BaFe11.9In0.1O19‐substituted M‐type hexaferrite are investigated. This solid solution is fabricated using “two‐step” topotactic reactions. It is determined through the X‐ray diffraction method that the crystal structure of this solid solution under normal conditions has hexagonal symmetry with P63/mmc space group (No. 194) with the unit cell parameters a = 5.8992(1) Å and c = 23.2275(7) Å. It is determined by the scanning electron microscope (SEM) researches that the average size of the grains is true d ¯ = 6 μm. It is determined by the vibration magnetometry that the ferrimagnet–paramagnet phase transition happens at around T C = 420 °C. Using differential scanning calorimetry (DSC), it is found that air and water molecules leave the sample surface up to 420 °C and the resulting oxygen anions appearing as a result of a solvothermal reaction fill the oxygen vacancies in the crystal structure at high temperatures up to 800 °C. The thermal transitions repeated in the high temperatures are established. The oxidation behavior of this compound is determined from thermogravimetric analysis (TGA) in a wide temperature range.

“…Moreover, over the past few years, studies related to the radiation resistance of various types of ceramics based on oxide or nitride compounds, which have several characteristics that allow them to be used in extreme conditions associated with high temperatures and high-dose radiation, have been of great interest [4,5]. One of the key properties of ceramic materials that allow them to be used as structural materials is their resistance to the accumulation of radiation damage and subsequent phase-structural transformations associated with the accumulation effects of structural distortions and deformation stresses in the damaged layer [6,7]. Unlike metal alloys and steels, in which the processes of martensitic transformations can be initiated during high-dose irradiation, which result into a sharp decrease in the strength properties of materials, such processes are not observed in ceramics in view of their structural features.…”

Study of the Influence of the Irradiation Flux Density on the Formation of a Defect Structure in AlN in the Case of the Effect of Overlapping of the Heavy Ion Motion Trajectories in the Near-Surface Layer

et al. 2023

The aim of this paper is to test the previously stated hypothesis and several experimental facts about the effect of the ion flux or ion beam current under irradiation with heavy ions on the radiation damage formation in the ceramic near-surface layer and their concentration. The hypothesis is that, when considering the possibilities of using ion irradiation (usually with heavy ions) for radiation damage simulation at a given depth, comparable to neutron irradiation, it is necessary to consider the rate factor for the set of atomic displacements and their accumulation. Using the methods of X-ray diffraction analysis, Raman and UV–Vis spectroscopy, alongside photoluminescence, the mechanisms of defect formation in the damaged layer were studied by varying the current of the Xe23+ ion beam with an energy of 230 MeV. As a result of the experimental data obtained, it was found that, with the ion beam current elevation upon the irradiation of nitride ceramics (AlN) with heavy Xe23+ ions, structural changes have a pronounced dependence on the damage accumulation rate. At the same time, the variation of the ion beam current affects the main mechanisms of defect formation in the near-surface layer. It has been found that at high values of flux ions, the dominant mechanism in damage to the surface layer is the mechanism of the formation of vacancy defects associated with the replacement of nitrogen atoms by oxygen atoms, as well as the formation of ON–VAl complexes.
