Dielectric characterization of microwave sintered lead zirconate titanate ceramics
(2016-10-01)
Highly reactive lead zirconate titanate powders (PZT) with different compositions were successfully synthesized by the oxidant-peroxo method (OPM) and used to prepare dense ceramic samples with composition near to the ...
Influence of polymer insertion on the dielectric, piezoelectric and acoustic properties of 1-0-3 polyurethane/cement-based piezo composite
(2019-11-01)
Cement/polyurethane based piezo composite was fabricated with 1-0–3 connectivity. Microstructural analysis shows that polyurethane (PU) acts as a binder, reducing the porosity and improving the matrix adhesion to the ...
Regressions of the dielectric constant and speed of sound of vegetable oils from their composition and temperature using genetic programming
(Elsevier, 2021-12)
The dielectric constant (DC) and speed of sound (SoS) have been measured in many studies on vegetable oils (VOs). These measurements can be applied for quality control, for the detection of contaminants, and in works related ...
Mechanical and electrical driving field induced high-frequency dielectric anomalies in ferroelectric systems
(Iop Publishing Ltd, 2007-09-26)
Polycrystalline or single-crystal ferroelectric materials present dielectric dispersion in the frequency range 100 MHz-1 GHz that has been attributed to a dispersive ( relaxation-like) mechanism as well as a resonant ...

INFLUENCE OF HIGH MICROWAVE DIELECTRIC-CONSTANTS ON THE LINESHAPE OF CONDUCTION-ELECTRON SPIN-RESONANCE
(Academic Press Inc. Jnl-comp Subscriptions, 1995-09-01)
Some synthetic metals show in addition to good conductivity, high microwave dielectric constants. In this work, it is shown how conduction-electron spin resonance(CESR) lineshape can be affected by these high constants. ...

Influence of micro- and nanoparticles of zirconium oxides on the dielectric properties of CaCu3Ti4O12
(2017)
This work presents the results of Zr oxide doping of a CaCu3Ti4O12 (CCTO) ceramic prepared by a solid-state reaction. Different stoichiometries (ZrO and ZrO2) and grain sizes (micro- and nanoparticles) were added as dopants ...
Ceramics fillers enhancing effects on the dielectric properties of poly (vinylidene fluoride) matrix composites prepared by the torque rheometer method
(2019)
The dielectric properties of ceramic-polymer composites were investigated using different lead-free ferroelectrics, 0.50[Ba(Zr0.2Ti0.8)O3]–0.50(Ba0.7Ca0.3)TiO3 (BZT-BCT) and 0.96(K0.48Na0.52) Nb0.95Sb0.05) O3–0.04Bi0.5(N ...
