The relativedielectric constant(εr) of a material indicates the value by which the capacity of a condensator in a vacuum increases when this material is brought between the plates of the condensator. The relative dielectric constant is calculated as the product of the dielectric constant (ε) an...
(12)C(ω)=ɛ′ɛoAd where ε′ is a constant of proportionality defined as the relative permittivity (dielectric constant) of the material between the electrodes, ε0 is a constant known as the permittivity of free space (1/3671×10−9 Farads m−1), A is the area of the electr...
In summary, a new class of high-entropy (La0.2Li0.2Ba0.2Sr0.2Ca0.2)Nb2O6-δ tungsten bronze ceramics has been successfully synthesized by solid-state reaction. The results show that dielectric properties of dielectric constants εr and dielectric loss tanδ are obviously affected by sintering tem...
Prinz1,3 Dielectrics are an important class of materials that are ubiquitous in modern electronic applications. Even though their properties are important for the performance of devices, the number of compounds with known dielectric constant is on the order of a few hundred. Here, we use Density...
Materials with high dielectric constant and high nonlinear dependence of the dielectric constant on applied voltage are promising candidates for high tunable dielectric devices. Ferroelectric materials are very exciting class of microwave materials because their dielectric constants depend nonlinearly on an ...
The dielectric study reveals the increase in value of dielectric constant from 10.8 to 42.3 as the filler content increased from 0 to 12 wt%. A pressure measurement set up was developed and voltage output was measured from the PVDF thin film sensor for variation in applied pressure. 展开 ...
12) of this class has drawn considerable interest for dielectric and ferroelectric application due to low leakage and fatigue free and high-remanent polarization as well as high-ferroelectric to paraelectric-phase transition temperature (Tc∼
whereKrepresents an empiric parameter andnrepresents the high-frequency slope of the AC conductivity ranging from 0 to 1[12]. DS can also reveal the dynamic changes in the dielectric constant and scanning frequency. It can provide a huge amount of information on the structure of matter, ion ...
It can be seen that La(Cr0.2Mn0.2Fe0.2Co0.2Ni0.2)O3 high-entropy ceramics have a giant dielectric constant, which is significantly larger than that of pure LaCrO3 ceramics (the dielectric constant is about 1500 when the test temperature is 40 °C [40]). The higher dielectric constant may...
On the basis of measurement results for the combustion temperature, it can be seen that all the analysed dielectric liquids and their mixtures qualify for class O. In turn, based on the net calorific value, only mineral oil and a mixture consisting of 95% MO and 5% LVNE value can be ...
