High dielectric constant and low temperature ferroelectric-phase-transition in Ca, Pb co-doped BiFeO3

Results in Physics, 2021
BiFeO3 was co-doped with (Ca, Pb) to obtain Bi1-x(Ca1/2Pb1/2)xFeO3 (x = 0, 0.1 and 0.3) and their structural, morphological, dielectric and ferroelectric properties were studied.

Dielectric properties of CaCu3Ti4O12 based multiphased ceramics [PDF]

, 2006
A “soft chemistry” method, the coprecipitation, has been used to synthesize the perovskite CaCu3Ti4O12 (CCT). Three main types of materials were obtained for both powders and sintered ceramics: a monophased consisting of the pure CCT phase, a biphased ...

Effects of Sn4+ and Ta5+ dopant concentration on dielectric and electrical properties of TiO2: Internal barrier layer capacitor effect

Results in Physics, 2022
The (Sn1/2Ta1/2)xTi1-xO2.0125 (SnT–TO) ceramics with x = 1.0–5.0 % were prepared by a standard mixed–oxide method. The sintered ceramics showed highly dense microstructures with a single phase of rutile–TiO2 structure.
