Abstract

ABSTRACT: Ceramics Na1- x Li x NbO3 ( x = 0.08, 0.1, and 0.2) were synthesized by conventional solid-state processing. The structural and dielectric measurements of these ceramics were performed in a temperature range from room temperature up to 600°C, frequency range from 100 Hz to 2 MHz and axial pressure to 1500 bar. The XRD investigations and micrographs reveal that the obtained samples have been well sintered. They possess pure perovskite structure and the grains are well formed. Dielectric investigations show that theaxial pressure greatly affects the intensity of the peaks and the ϵ(T) peaks became diffused and shifted to lower temperatures. The values of tanδ change also significantly. The obtained results of the performed investigations of this materials show that the Na1- x Li x NbO3 ( x = 0.08, 0.1, and 0.2) are a good candidate for lead-free electroceramics.
