“…Therefore, there is a considerable interest in the search of new dielectric materials with low sintering temperature [35,36]. Our recent work stated a particular point concerning the sintering temperature for Sr 1 x (Na 0.5 Bi 0.5 ) x Bi 2 Nb 2 O 9 pellets at 800 [37].…”

Abstract:In this study, we investigated the effect of sintering temperature on densification, grain size, conductivity and dielectric properties of Sr 1 x (Na 0.5 Bi 0.5 ) x Bi 2 Nb 2 O 9 ceramics, prepared by hydrothermal method. Pellets were sintered at different temperatures. Density increased with sintering temperature, reaching up to 96% at 800 . A grain growth was observed with increasing sintering temperature. Impedance spectroscopy analyses of the sintered samples at various temperatures were performed. Increase in dielectric constant and in Curie temperature with sintering was discussed. Electrical conductivity and activation energy were calculated and attributed to the microstructural factors.

“…The intensive efforts have been carried out to improve the characteristic piezoelectric properties of BNT and BKT by doping of metal ion species 9,10) and changing of the sintering conditions. 11,12) However, such efforts to obtain BNT-and BKT-based ceramics have been mainly investigated by solid phase sintering systems, expect for several examples. [13][14][15][16] In contrast, generally speaking, liquid-phase synthesis of such ceramic particles has large advantages to obtain highly purified and homogeneous powders controlled in size, crystalline diameter, and morphology.…”

(BKT) fine particles with narrow size distribution were directly prepared as a single phase from a suspension of TiO 2 anatase nanoparticles mixed with Bi(OH) 3 in aqueous alkaline metal hydroxides solutions by highly condensed hydrothermal method at 200-250 C for several hours. It was investigated that the effect of particle mean size on the piezoelectric properties of thus obtained BNT and BKT fine particles.

“…However, this advantage is offset by the high E C (73 kV/cm) that is known to cause problems during poling [132]. There is also a high tendency of the compound to decompose during sintering by evaporative losses of volatile Na and Bi [133].…”
