CaCu3Ti4O12 ceramics from co-precipitation method: Dielectric properties of pellets and thick films [PDF]

open access: yes, 2009
Dielectric properties of CaCu3Ti4O12 (CCTO)-based ceramics and thick films (e ∼50m) prepared from powders synthesized by a soft chemistry method (co-precipitation) are presented and discussed.

Grain Growth-Controlled Giant Permittivity in Soft Chemistry CaCu3Ti4O12 Ceramics [PDF]

open access: yes, 2007
We report a dielectric constant of up to 5.4105 at room temperature and 1 kHz for CaCu3Ti4O12 (CCTO) ceramics, derived from multiphase powders (coprecipitation products), made by a ‘‘chimie douce’’ (coprecipitation) method, and then sintered in air.

Dielectric properties of CaCu3Ti4O12 based multiphased ceramics [PDF]

open access: yes, 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 ...

Effect of UV radiation on dielectric properties of PU/nano-TiO2 composites

open access: yesIraqi Journal of Physics, 2019
The dielectric constant of most polymers is very low; the addition of TiO2 particles into the polymers provides an attractive and promising way to reach a high dielectric constant.

Interface Dielectric Constant of Water at the Surface of a Spherical Solute

open access: yes, 2022
Interface dielectric constant is used to quantify polar response of water interfacing a spherical solute. This interfacial parameter, affected by the interfacial structure within about two solvation layers, is fundamentally distinct from the bulk ...
