| Popis: | A batch of glasses with composition 20BaO-10Bi2O3-(70-x)B2O3 – xTiO2 (x = 0, 0.2, 0.4, 0.6, 0.8 and 1 mol %) were prepared by melt quenching technique. Glass transition temperature (Tg) for all samples were estimated and observed that Tg decreases with increase of TiO2 content. The structural modifications occurring in the glass network have been examined by Fourier transform infrared spectroscopy. The bands below 500 cm−1 indicates the normal vibrations of Ti-O. Dielectric properties viz., dielectric loss, dielectric constant were analysed with variation of frequency and identified that as frequency increases, the dielectric constant decreases but A.C. conductivity increases in all samples. Incorporation of TiO2 leads to alter the dielectric constant at any particular frequency, hence these glasses can be used in electrical devices. |
