Original Abstract

Lead-free piezoceramic with the composition of 0.89BaTiO(3)-0.11BaSnO(3) (BT-11BS) was prepared by solid-state reaction followed by conventional sintering achieving nearly full density. The influence of sintering temperature on electrical properties were thoroughly investigated, implying a significant role in achieving best properties, which were obtained between 1420 and 1440 degrees C. The addition of SnO2 in BaTiO3 solid solution promoted grain growth, eventually resulting in the grain sizes between 145 and 216 mu m. An ultra-high dielectric permittivity >5.0 x 10(4) and related dielectric loss of 3.1 % at similar to 40 degrees C was achieved. A high value of quasi-static piezoelectric constant (d(33)) of 693 pC/N and the converse piezoelectric constant (denoted as d(33)*) reached a value of up to 831 pm/V in the frequency range between 10 and 110 Hz. The transmittance of similar to 25 % in the visible region and similar to 40 % in the infrared region together with good electromechanical properties showcasing a unique combination for this material.
