CO oxidation on ceria studied by electrochemical impedance spectroscopy
(2020-09-14)
Article
Open AccessElectrochemical impedance spectroscopy technique has been widely used to analyze the electrical properties of a large number of materials. In this study, the electrical properties of CeO2 pellets under CO oxidation conditions ... -
Elastic, dielectric and electromechanical properties of (Bi0.5Na0.5)TiO3-BaTiO3 piezoceramics at the morphotropic phase boundary region
(2017-01-05)
Article
Open AccessA systematic study of the functional properties of the (1-x)(Bi0.5Na0.5)TiO3–xBaTiO3 (BNT-xBT) piezoceramic system for 0.05 = x = 0.07 is performed. The samples are obtained through the conventional solid-state route. The ... -
Growth and physical properties of highly oriented La-doped (K,Na)NbO3 ferroelectric thin films
(2015-02-27)
Article
Open AccessLead-free (K,Na)NbO3 (KNN) and La doped (K,Na)NbO3 (KNN-La) thin films are grown on SrTiO3 substrates using the chemical solution deposition method. The effect of adding different amounts of Na and K excess (0-20 mol%) is ... -
Improving the functional properties of (K0.5Na0.5)NbO3 piezoceramics by acceptor doping
(Elsevier, 2015-01-01)
Article
Open AccessZrO2 and TiO2 modified lead-free (K0.5Na0.5)NbO3 (KNN) piezoelectric ceramics are prepared by a conventional solid-state reaction. The effect of acceptor doping on structural and functional properties is investigated. A ... -
Influence of the type of rare-earth cation on electrical properties of Ba(Zr,Ti)O3 ceramics
(2011-02)
Article
Open AccessEn este artículo es investigado el efecto del radio iónico de diferentes cationes de tierras raras sobre las propiedades eléctricas del compuesto Ba(Zr,Ti)O3. La cerámica BaZr0.09Ti0.9O3 fue dopada con iones de Gd3+, Pr3+ ... -
Phase transition characteristics and dielectric properties of rare-earth (La, Pr, Nd, Gd) doped Ba(Zr0.09Ti0.91)O-3 ceramics
(2010-02-15)
Article
Restricted access - publisher's policyA-site deficient rare-earth doped barium zirconate titanate (BZT) ceramics (Ba1−yLn2y/3)Zr0.09Ti0.91O3 (Ln = La, Pr, Nd, Gd) are obtained by a modified solid-state reaction method. Perovskite-like single-phase compounds ... -
Tailoring the microstructure by a proper electric current control in flash sintering: The case of barium titanate
(Elsevier, 2022-10)
Article
Open AccessFlash sintering is arousing growing interest because high-density ceramics can be obtained at lower temperatures and shorter dwell times than conventional sintering. However, not only temperature and dwell times should be ...
