dc.description.abstractFerroelectric materials are key to many technologies due to their vivid properties such as low Curie temperature, high permittivity etc. Ferroelectric material BaTiO3 is the most widely investigated material. Due to a high permittivity BaTiO3, enables enhancement of the volumetric efficiency of multi-layer ceramic capacitors (MLCCs). In this study BaTiO3 has been synthesised by the co-precipitation method of chemical synthesis to get reduced particle/ crystallite size as compared to well existing synthesis methods such as solid state, sol-gel, hydrothermal methods. The XRD results reveal the proper formation BaTiO3 along with crystalline size of 19.45 nm calculated from Scherrer formula, while SEM micrograph shows the agglomerated spherical particle of average size of 100-150 nm. The dielectric losses are more at 30oC as compared to 100oC for same frequency set. Variation of dielectric loss is checked at different frequencies in a common set of temperature shows that dielectric loss is very high for 10 KHz frequency as compared to 500 Hz and 1 KHz. The dielectric constant is more at 100oC than at 30oC for same frequencies. The dielectric constant is more for 500Hz and 100 KHz as compared to 10 KHz for same temperature set values. The resistance is higher at 30oC as compared to 100oC. The impedance remains almost same for both temperatures. The resistance and impedance decrease with increase in frequency.en_US
