Abstract

A new solid solution composition K2Ba4Li1.2Zn0.4Nb 9.6O30 was synthesized by solid-state reaction method. The results of scanning electron microscopy and X-ray diffraction analysis showed that the solid solution forms tetragonal filled tungsten-bronze structure. Dielectric studies show that the dense ceramics of the composition has high dielectric constant (866) at 1 MHz and low loss. The ferroelectric phase transition of diffuse-type was observed in the experiments. The diffusivity calculated of the compound is 1.1.
