Article Synopsis
  • BaCaTiO ceramics were synthesized using a straightforward solid-state reaction, focusing on how different sintering temperatures affect their structure and properties.
  • XRD analysis showed that a dominant tetragonal phase forms at sintering temperatures of 1400 °C and 1450 °C, with those temperatures producing single-phase materials, while other temperatures resulted in some orthorhombic phase presence.
  • Higher sintering temperatures improved grain size and boundary formation, resulting in increased electric permittivity up to 1400 °C, but a drop at 1450 °C, while also affecting the material's phase transition characteristics and thermal properties.

This investigation focuses on the impact of Sm dopants on BaBiNbO (BBN) ceramics. These ceramics were obtained using the traditional solid state reaction approach. Techniques like scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDS) were employed to explore the structure and morphology of the ceramics.

Herein this study, the polycrystalline nature of the Aurivillius type structure is studied; primarily, the main objective is to observe the influence of dopant Pr at the Ba-site of BaBiNbO (BBN) ceramics. The ceramics under investigation were fabricated via the conventional solid-state reaction method. Scanning electron microscopy (SEM) and energy dispersion spectroscopy (EDS) techniques were used to analyse their morphological structure.

The Pr-doped solid solutions from (Ba,Ca)(Ti,Zr)O (BCTZO) system were successfully synthesized using an efficient and low-energy consuming route-the Pechini method combined with the sintering at relatively low temperature (1450 °C). The obtained materials were characterized by means of X-ray diffraction (XRD) and scanning electron microscopy (SEM). The dielectric properties were systematically studied.
