“…These materials exhibit good ferroelectric and piezoelectric properties [1]. However, Pb-based materials can cause environmental pollution as PbO is highly toxic and accounts for a large proportion of the initial mixture (60% of PbO) [1,2]. Therefore, lead-free ceramic systems with good ferroelectric and piezoelectric properties must be developed to replace lead-based ceramic systems.…”

Lead-free (K0.48Na0.48Li0.04)(Nb0.95Sb0.05)O3 (KNLNS) ceramics have been successfully optimized for the calcination and two-step sintering temperatures. The experimental results reveal that the KNLNS powder calcined at 850 or 900 °C presented a pure perovskite phase with an orthorhombic phase. The particle size was in the range of 0.1–0.4 m. The two-step sintering temperature (range: 950 to 1100 °C) significantly affects the structure, microstructure, and electrical properties of KNLNS ceramics. The presence of a pure perovskite phase with good crystallization is observed in all samples. The microstructure was researched by varying the two-step sintering temperature to obtain a dense microstructure and a clear grain boundary in order to optimize their piezoelectric properties. The best electrical properties of KNLNS ceramics were recorded at the optimized temperature of 1050 °C (density (): 4,35 g/cm3; electromechanical coupling factor (kp): 0.33, kt: 0.35; dielectric constant (εr): 849; dielectric loss (tanδ): 0.073; maximum dielectric constant (max at TC): 6659; piezoelectric constant (d33): 195 pC/N; remanent polarization (Pr): 16.1 µC/cm2; energy storage density (Wrec): 0.36 J/cm3; energy storage efficiency (): 48.1%; t2 = 4 h), proving the efficacy of the two-step sintering technique
