Nanocrystal composites cement/BaCO3/Fe2O3 for improved X ray shielding characteristics: Stability structural properties

Nanocrystal composites BaCO3/Fe2O3 were prepared using mechanical alloying for up to 56 h. From the analysis of X-ray difraction (XRD) spectra, we choose three samples with the high concentration of BaFe12O19 phase for producing composites cement/BaCO3/Fe2O3. Refractive index (n), extinction coefcient (k), real (ǫ1) and imaginary part (ǫ2) dielectric function, and energy loss function (Im(−1/ǫ)) were determined from the quantitative analysis of Fourier transform infrared (FTIR) spectra using Kramers–Kronig relation. Radiation parameters were determined from X-ray mobile test data and then compared with theoretical calculation from XCOM database. We found the stable structural properties of all composites, indicated by similar crystallite size for before and after X-ray irradiation. The HVL for the highest energy is in the range of 0.280 to 0.291 cm indicated high potentials and efective alternative material for X-ray radiation shielding in future for development new radiology room.
