“…Lead titanate when combined with other oxides can form a series of solid solution materials such as Pb(Zr, Ti)O 3 (PZT) and (Pb, La) (Zr, Ti)O 3 (PLZT), with potential applications in sensors, capacitors and non-volatile memories. Some authors have investigated PT materials modified by various additives [11][12][13][14]. Lead titanate (PT) ceramics modified by rare earth elements and alkaline earth elements are extremely good for high frequency applications [15].…”

A novel two-step sol-gel method was used in order to synthesize PbTiO 3 nanoparticles with aid of Pb(CH 3 COO) 2 Á2H 2 O, and Ti(OC 4 H 9 ) 4 (TNBT) as the starting reagents in the presence of ethanol as the solvent. To the best of authors knowledge, it is first time that benzene-1,3,5-tricarboxylic acid [C 6 H 3 (COOH) 3 ] (trimesic acid) use as a chelate agent in produce lead titanate nanoparticles. Besides, to examine the effect of some reaction parameters such as surfactants, reaction temperature, and molar ratio of TNBT to trimesic acid on the morphology and chemical structure of final products several tests were performed. The as-synthesized PbTiO 3 nanoparticle was utilized as photo-anode material for the fabrication of FTO/PbTiO 3 /CdS/Pt-FTO and photocatalyst for decolonization of rhodamine-B (RhB) and methylene blue (MB) to investigation its light harvesting applications. Furthermore, according to the XRD results, only in the presence of trimesic acid as the chelate agent pure PbTiO 3 nanoparticle was synthesized. The photocatalyst results reveal that the maximum decolorization of 88 and 82 % for RhB and MB occurred with PbTiO 3 nanoparticles catalyst in 40 min of stirring under ultraviolet light irradiation, respectively.

Nanocrystalline PbTiO3 in tetragonal form has been successfully prepared via a newly developed environmentally friendly coprecipitation process. The formation process of lead titanate from the PbC2O4·TiO2 precursor was monitored using DTA–TG, XRD, FT-IR, and TEM techniques. XRD showed the phase transition of less stable tetragonal PbO decomposition intermediate to a more stable orthorhombic structure by raising the calcination temperature. For the precursor calcined at 600 °C, only XRD lines characteristic of nanocrystalline tetragonal PbTiO3 are detected. TEM of PbTiO3 nanocrystals showed agglomerates with diameters in the range 85–90 nm. Consistent with the TEM result, the grain size estimated using surface area measurements indicated a high degree of particle agglomeration. FT-IR measurements gave results which are in close agreement with those revealed by XRD technique. The ac conductivity of PbTiO3 depends on the dielectric property. The kinetics of the nonisothermal TG curves for the precursor decomposition was carried out assuming various solid-state-reaction models and applying three different computational methods. The data analysis showed that the presence of TiO2 during oxalate decomposition reaction does not alter the decomposition mechanism; it drastically affects the activation parameter values.
