Preparation of BiFeO3-BaTiO3 Based Thick Films by Screen Printing

Article Preview

Abstract:

0.67BiFeO3-0.33BaTiO3 thick films were prepared by screen printing pastes prepared by kneading the 0.67BiFeO3-0.33BaTiO3 powder in a three-roll mill with an organic vehicle. The thick films were fired with Pt bottom electrodes and ZrO2 substrates to investigate the influence of firing temperature. The microstructures and ferroelectric properties of the thick films were examined and compared with the bulk ceramics. A remanent polarization of 32.0 μC/cm2 and coercive field of 28 kV/cm were obtained for a thick film with the addition of 0.5 wt% MnO that was fired at 1050 °C.
