Effect of SrTiO₃ Nano-Crystals on the Dielectric Properties of Na_0.47K_0.47Li_0.06NbO₃ Ceramics by Seed-Induced Method

Abstract:

A solid-state reaction method is generally used to fabricate ceramics. This work studies the influence of heterogenous nano-crystallites on electrical properties of lead free Na_0.47K_0.47Li_0.06NbO₃ (NKLN) ceramics by adding SrTiO₃nano-crystals as the initial phase of reaction. The lead-free piezoelectric ceramics were synthesized by the seed-induced method. The SrTiO₃nano-crystals used as seeds were prepared by molten salt technique. The seed content was varied from 0 to 10.0 mol%. The investigation reports microstructure and electrical properties of ceramics. The XRD showed a mixed tetragonal and orthorhombic phase structure. T_c decreasing with increased SrTiO₃nano-crystal concentration.
