“…BTO is usually prepared using a conventional solid state reaction at a calcinations temperature above 1000 o C. However, this route has several disadvantages, such as inhomogeneity, non-uniformity of grain morphology, high impurity content, a lack of reproducibility, and a necessity for repeated grinding [6]. Moreover, the densification at a high sintering temperature is not suitable for ferroelectric applications, because the loss of bismuth ions at high temperature results in the formation of secondary phases [7].…”

Bi4Ti3O12 (BTO) powders were synthesized using soft combustion techniques, specifically known as Solution Combustion Synthesis (SCS) and Low-temperature Combustion Synthesis (LCS). XRD results showed that the single phase BTO was obtained following calcinations at 800ºC for the sample prepared using SCS; compared to after combustion, for the sample prepared using LCS. The TG/DTA showed a combustion temperature of around 252 - 280ºC, which became stable with a single phase BTO at 500ºC and above. Sintering was carried out at 1,100ºC for 3 h, to determine the microstructures, grain orientation, relative density, dielectric, and ferroelectric properties, of the bulk ceramics. It was found that the bulk ceramics prepared using SCS exhibited elongated-like grains, strong (117)-preferred grain orientation, a relative density of 93.3%, εr = 320 - 360, tan δ = 0.03 - 0.1, Pr = 6.8 μC/cm2, and Ec = 20 kV/cm. Meanwhile, the bulk ceramics prepared using LCS showed plate-like grains, strong c-preferred grain orientation, a relative density of 83%, εr = 143 - 195, tan δ = 0.01 - 0.38, Pr = 5.9 μC/cm2, and Ec = 30 kV/cm

Bismuth I 5400 Citrate-Oxide Method to Prepare SrBi4Ti4O15 Powders and Ceramics. -The title compound is prepared from mixtures of SrCO 3 , Bi 2 O 3 , TiO 2 , and citric acid (H2O, ball milling, 4 h; drying at 120°C, 8 h). The obtained gels are calcined at 500, 550, and 600°C for 2 h under oxygen. After combustion, the gels transform into pure SrBi4Ti4O15 powder without the formation of any intermediate phase. Powders calcined at 550°C are used to prepare ceramics with higher density and better piezoelectric properties. The citrate-oxide method is an efficient, quick, and simple method for mass production of ceramic oxide powder. -(XU*, Z.; CHU, R.; HAO, J.; LI, G.; YIN, Q.; J.
