“…Addition of SiO 2 as an additive is reported to assist grain growth, as a result the grain became more uniform [2]. Furthermore, using SiO 2 : PbTiO 3 weight ratios from 0.03:0.97 to 0.05:0.95 decreases the vacancies of sample and the sintered body became denser.…”

“…Perovskite group with a general formula AB 3 has a corner-linked network of oxygen octahedral, creating an octahedral cage (B-site) and the interstices (A-sites). Among the AB 3 group, PbTiO 3 have attracted attention due to its potential in a wide range of hightemperature and high-frequency applications [2,3]. However it is difficult to synthesize a crack free dense PbTiO 3 .…”

Abstract. Ferroelectric materials have found many applications in a wide range of capacitors, transducers, sensors, light valves and motors. Their properties are related to the routes they are processed. Ferroelectric materials in their bulk polycrystalline form are difficult to fabricate in shapes and sizes suitable for device applications. This is due to cracking occurs during sintering process. This has lead to research being undertaken to produce a crack free dense polycrystalline ferroelectric samples by using additives. Therefore in this study PbTiO 2 powders with addition of SiO 2 as an additive were synthesized by solid-state reactions using different SiO 2 :PbTiO 3 weight ratios (0.1:0.9, 0.05:0.95 and 0.03:0.97). Structural and morphological changes were studied using XRD and SEM with regard to after the addition of SiO 2 at sintering temperatures 900 • C, 1000 • C and 1100 • C.

“…For instance, the commercial piezoelectric materials, a-quartz (SiO 2 ) and lead titanate (PbTiO 3 ) are the core materials in a great number of devices such as actuators, sensors, and transducers [1,2]. As typical magneticoptical materials, Yttrium iron garnet (Y 3 Fe 5 O 12 , YIG) and doped-YIG have been widely applied in tunable microwave devices, circulators, isolators, phase shifters, nonlinear devices, etc.…”

“…It possesses a high Curie temperature and low dielectric constant, which makes it attractive for high-temperature and high-frequency piezoelectric applications. 2 It is cubic and paraelectric above the Curie temperature, while its tetragonal structure is stable below the Curie temperature. 3 More recently, PT nanostructures have become more and more attractive because they are promising candidates for high-density, nonvolatile information storage and scanning probe based ferroelectric mass storage.…”

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.
