Dielectric and ferroelectric properties of BST ceramics obtained by a hydrothermally assisted complex polymerization method

Comparison between dielectric and pyroelectric properties of PZFNT and BST type ceramics

“…7. Phase transition temperatures and dielectric constants are similar to those reported in the literature [16].…”

“…This is the consequence of a very low remnant polarization of BST and of a small coercive field of PZFNT compared to the maximum applied field. Capacitance measurements were registered at 1 kHz in vacuum, on a broad temperature range from −200°C to 200°C, in order to determine the dielectric constant and to identify the phase transitions [16]. The temperature dependence of the dielectric constant is represented in Fig.…”

“…Pyroelectric materials with perovskite structure such as BaTiO 3 and Pb(Zr,Ti)O 3 (PZT) have been widely used for capacitor and actuator applications near room temperature [19]. For the pyroelectric applications there is only one significant parameter, the value of the total pyroelectric coefficient, defined by the relation [16]:…”

Dielectric relaxation and predominance of NSPT and OLPT conduction processes in Ba0.9Sr0.1TiO3

“…Structural properties of BST were determined by X-ray diffraction (XRD) patterns analysis. c=3.99 Å reported for BST [8].…”

“…The microstructure and dielectric properties of BST both in bulk and in thin films forms have been reported by several authors [7,8]. However, the literature survey shows limited reports on the relaxation processes and conduction mechanism in BST system, although the understanding of these features is very important to realize the practical applications.…”
