Abstract
Abstract The 0-3 connectivity lead-free barium calcium stannate titanate (BCTS)-Portland cement (PC) composites were produced by pressing and curing techniques. The effect of BCTS ceramic content on microstructure and dielectric properties of composites were studied. Scanning electron microscope images at the interfacial zone of composites showed denser microstructure between Portland cement matrix and BCTS ceramic. The dielectric constant and dielectric loss of BCTS-Portland cement composites were also found to depend on the frequency in the range tested. The dielectric results indicate that the BCTS ceramic can improve the dielectric constant (lower dielectric loss) in composites. The dielectric constant followed the cube model.
期刊介绍：
Ferroelectrics Letters is a separately published section of the international journal Ferroelectrics. Both sections publish theoretical, experimental and applied papers on ferroelectrics and related materials, including ferroelastics, ferroelectric ferromagnetics, electrooptics, piezoelectrics, pyroelectrics, nonlinear dielectrics, polymers and liquid crystals.
Ferroelectrics Letters permits the rapid publication of important, quality, short original papers on the theory, synthesis, properties and applications of ferroelectrics and related materials.
