Abstract
The effect of BaTiO3 concentration on borate glass were investigated, with various BaTiO3 content and different ZnO-B2O3 solution as the sintering aids by melting quenching technique. X-ray diffraction technique confirmed the formation of powder mixtures. The density of glass is increased with increasing the amount of BaTiO3 concentration, while molar volume and refractive index were slightly altered. Absorption spectra were measured, and optical band gap were determined. Absorption bands were not discovered in the visible light spectrum. The dielectric behavior which is also observed of BaTiO3-ZnO-B2O3 system were systematically investigated. The dielectric of BaTiO3 concentration on borate glass with good permittivity and low dielectric loss were obtained at high concentrations the amount of BaTiO3. Furthermore, radiation shielding properties were calculated and found better when increasing of BaTiO3. This developed glass could be used for transparency radiation shielding materials.
