Tailoring the microstructure by a proper electric current control in flash sintering: The case of barium titanate

Flash sintering is arousing growing interest because high-density ceramics can be obtained at lower temperatures and shorter dwell times than conventional sintering. However, not only temperature should controlled during flash but also parameters such as the electric field current considered. Controlling all processing allows comprehensive control of microstructure and, consequently, functional properties improved. In this work, it evidenced that an exhaustive a crucial factor for tailoring BaTiO 3 ceramics. The results reveal most suitable way to process by using non-linear profiles better densification improved grain growth achieved. Although focus on , work offers new pathway tailor sintered ceramics, which may extended other materials.
