A ferroelectric-paraelectric transition is evidenced from the variation of the dielectric constant with temperature. Barium titanate is one of the most studied perovskite materials owing to its ability to the substitution in both sites, to its high dielectric constant and to its stability.
As oxide perovskite material, barium titanate BaTiO 3 (BTO) is widely studied by researchers owing to its physical properties [, , ]. The particular ferroelectric and dielectric properties of this material ensure its potential in a number of dielectric applications.
Besides, the incorporation of the Ca2+ ion into barium titanate results in a slight decrease in the value of Z’. At high frequency, the values of Z’ merge for all temperatures which indicates the existence of space charge polarization .
The variation of the conductivity as a function of frequency is presented in Fig. 8 in order to study the effect of calcium incorporation into the BTO lattice. The spectrum can be divided into two regions. In the range of 40-10 4 Hz, the conductivity is almost independent of frequency, but it shows an increase with the rise of temperature.
Multilayer ceramic capacitors (MLCCs) for energy storage applications have received increasing attention due to the advantages of ultralow equivalent series inductance, equivalent series resistance, good frequency characteristics, strong voltage overload ability, and stable operability at high temperatures.
The recoverable energy density of capacitors can be measured and calculated by the pulse discharge current curves in a high-speed switch circuit with load ( W d = R ∫ I ( t 2) d t / V, R and V are loaded resistance and the effective volume of the capacitors, respectively).

We propose a high-entropy design in barium titanate (BaTiO 3)–based lead-free MLCCs with polymorphic relaxor phase. This strategy effectively minimizes hysteresis loss by lowering the domain-switching barriers and enhances the breakdown strength by the high atomic disorder with lattice distortion and grain refining. Benefiting from the synergistic effects, we …
Barium titanate (BaTiO 3) is a synthetic crystal used in electromechanical transducers and multilayer ceramic capacitors.
