“…Replacing the elements with oxide compounds is a well-known technique to improve electrical properties of BNT ceramics [7,8]. For example, Bhoowadol Thatawong et al [9] synthesised Bi 0.47 Na 0.47 Ba 0.06 TiO 3 (BNBT) ceramics by the solid-state combustion technique with a calcination temperature of 750°C for 2 h and a sintering temperature of 1150°C for 2 h.…”

“…For example, Bhoowadol Thatawong et al.

The BNBT ceramics exhibited coexisting rhombohedral and tetragonal phases in a ratio of 53:47 and a high density (5.84 g/cm 3 ), an excellent maximum dielectric constant (ε m = 8405), good ferroelectric properties (P r = 28.2 µC/cm 2 and E c = 22.1 kV/cm) and a high piezoelectric coefficient (161 pC/N) were obtained.

This report investigates the effect of firing temperatures on the phase formation, microstructure, electrical, and energy storage properties of lead-free Sr0.3(Bi0.7Na0.67Li0.03)0.5TiO3 (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 ( εmax = 4667), polarisation ( Pmax = 28.80 µC/cm2) and energy density ( W = 0.95 J/cm3), with a breakdown strength of 70 kV/cm, were achieved from the sample sintered at 1175°C.
