| dc.description.abstract | This report investigates the effect of firing temperatures on the phase formation, microstructure, electrical, and energy storage properties of lead-free Sr<inf>0.3</inf>(Bi<inf>0.7</inf>Na<inf>0.67</inf>Li<inf>0.03</inf>)<inf>0.5</inf>TiO<inf>3</inf> (SBNLT) ceramics, synthesised by combustion technique. The samples were calcined between 700°C and 900°C for 2 h and sintered between 1100°C and 1200°C for 2 h. The ceramics exhibited coexisting rhombohedral and tetragonal phases, which were confirmed by the Rietveld refinement technique. A morphotropic phase boundary (MPB) of the rhombohedral and tetragonal phases, with a ratio of 49:51, was obtained at the sintering temperature of 1175°C. The highest maximum dielectric constant (ε <inf>max</inf>= 4667), polarisation (P <inf>max</inf>= 28.80 µC/cm<sup>2</sup>) and energy density (W = 0.95 J/cm<sup>3</sup>), with a breakdown strength of 70 kV/cm, were achieved from the sample sintered at 1175°C. | |
