“…Perovskite ceramics are widely used in many applications, such as sensors, transformers, and actuators [1][2]. The lead-based ceramics such as lead zirconatetitanate (PZT) and lead magnesium niobate-lead titanate (PMN-PT) have excellent properties [3]. However, lead oxide has effects on the environment and is very toxic.…”

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 Na0.47K0.47Li0.06NbO3 (NKLN) ceramics by adding SrTiO3 nano-crystals as the initial phase of reaction. The lead-free piezoelectric ceramics were synthesized by the seed-induced method. The SrTiO3 nano-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. Tc decreasing with increased SrTiO3nano-crystal concentration.
