Abstract
This work has been performed to explore the impact of the incorporation of the inorganic material Barium-Titanate BaTiO3 in the matrix of calciborosilicate glass doped with cadmium cations. Different amounts of BaTiO3 have been introduced to the pure cadmium-calciborosilicate glass at the expense of SiO2 according to the following chemical formula: 30mol%B2O3+20mol%CaO+25mol%CdO+(25−x)mol%SiO2+xmol%BaTiO3 where x = 0, 3, 6, 10. The suggested samples have been obtained using the fast quenching method from their melts at 1250 °C. X-ray diffraction XRD, and FTIR spectra have been used for the structural characterization process of the obtained solids, where the amorphous natures of all samples were confirmed. The increase of BaTiO3 caused the glass’ bulk density to increase from 4.33 g/cm3 (x = 0) to 4.45 g/cm3 (x = 10), as well as it caused an increase in the optical edge, direct bandgap, indirect bandgap, and Fermi energy. For all samples, the optical transmittance, as well as the optical absorbance were not affected by the photon energies in the UVregion, so these samples can be nominated to use as UV- blockers. Moreover, the shielding parameters indicated that the studied cadmium calciborosilicate glass sample with no BaTiO3 is a superior neutron shielding material, because it has the largest value for the effective neutron fast cross-section, while the opposite for gamma where the sample containing the highest content of BaTiO3. It is less valuable for the half-value layer and highest LAC. So we recommend using glass containing 3% of Barium-Titanate BaTiO3 as a radiation shielding material with less size.
