“…It is possible that it was volatized due to high firing temperature. This result is consistent with the literature which reports that the secondary phase in BKT decomposed at 1120 1C [23].…”

“…42,270,271 Although the sinterability of the BNT-based materials does not seem to be a major problem for their scalability, Bi and Na volatility should be considered during synthesis. 272,273 BNT is promising for piezoelectric applications; however, its high and conductivity make the poling difficult and restrict its applicability. The BNT-BT 270 and BNT-(Bi 1/2 K 1/2 )TiO 3 274 binary solid solutions have attracted a considerable amount of research due to promising small signal piezoelectric properties around the MPB.…”

“…The sintering temperatures of (1x)BaTiO 3  xM 0.5 Bi 0.5 TiO 3 (M = Li, Na, K) solid solutions are higher than 1300 ℃, and considerable losses of alkali metals and bismuth are observed, which lower the Curie temperature of solid solutions [20,21]. Compared to the traditional solid state reaction technique, oxalate coprecipitation method can significantly reduce the sintering temperature of BaTiO 3 powders [2225] and metal losses in (1x)BaTiO 3 xM 0.5 Bi 0.5 TiO 3 (M = Li, Na, K) solid solutions.…”

(1x)BaTiO 3 -xM 0.5 Bi 0.5 TiO 3 (M = Li, Na, K) solid solutions were prepared using BaTiO 3 pre-synthesized by oxalate method. The stability limits of (1x)BaTiO 3 -xLi 0.5 Bi 0.5 TiO 3 solid solutions have been established. It was shown that increase in M 0.5 Bi 0.5 TiO 3 concentration results in reduction of ceramic grain size in the (1x)BaTiO 3 xM 0.5 Bi 0.5 TiO 3 (M = Li, Na, K) system. It was found that the positive temperature coefficient of resistance (PTCR) effect in lead-free materials is due to the presence of a semiconductor core, which is formed by sintering under reducing atmosphere, and dielectric grain boundaries, formed on additional oxidation in air. The use of barium titanate, pre-synthesized by oxalate method, in the synthesis of solid solutions reduced the sintering temperature of ceramics compared with solid state reaction technique. By comparing the electrical properties of the synthesized lead-containing and lead-free materials, it has been shown that lead-free materials exhibit better electrical properties for practical use compared with lead-containing materials.
