Abstract:Ca 2 Nd 4 Ti 6 O 20 , a layered perovskite structured material was synthesized via a chemical (citrate sol-gel) route for the first time using nitrates and alkoxide precursors. Phase analysis of a sample sintered at 1625°C revealed the formation of an orthorhombic (Pbn21) symmetry. The microstructure of the sample after sintering comprised rod-shaped grains of a size of 1.5 to 6.5 µm. The room temperature dielectric constant of the sintered sample was 38 at 100 kHz. The remnant polarization (P r ) and the coer… Show more
