This study investigated the structural and radiation shielding properties of two groups of perovskite ceramics, analyzing their structure using Fourier transform infrared and X-ray diffraction. Different radiation shielding parameters were used to assess their ability to absorb radiation within a specific energy range. The results showed that BaTiO3-ZrO2 had excellent gamma-ray stopping capacity, while SrMnO3-TeO2 was effective in neutron prevention.
Recently, the use of ionizing radiation in various fields leads to an increased demand for shielding materials. This work aims to study the structural and radiation shielding properties of two groups of perovskite ceramics. Fourier transform infrared and X-ray diffraction were utilized to investigate current samples' structure, and various radiation shielding parameters were determined to explore the current samples' ability to absorb radiation within an energy range from 0.284 to 2.506 MeV using the Phy-X program. The Fourier transform infrared results revealed one vibration band for BaTiO3-ZrO2 located at 507 cm(-1), two bands centered at 835 and 520 cm(-1) for the BaTiO3-Mo sample, and five bands located at 435, 520, 539, 615, and 775 cm(-1) for SrMnO3-ZnO and SrMnO3-TeO2. Simultaneously, the X-ray diffraction displays the hexagonal phase for SrMnO3 and the tetragonal phase for BaTiO3 samples. The BaTiO3-Mo sample has the highest density, packing density, and Poisson's ratio compares with other samples. According to gamma shielding results, the SrMnO3-ZnO and BaTiO3-ZrO2 samples appear the lowest and highest absorption ability, respectively. On another side, the SrMnO3-TeO2 sample has the highest removal cross-section for fast neutrons. From obtained results, it can be concluded that the BaTiO3-ZrO2 sample has an excellent capacity to stop gamma-ray, while SrMnO3-TeO2 can be used to prevent neutrons.
