“…With increase in the measuring frequency the observed decrease in dielectric constant (ε) and loss tangent (tan δ), and increase in the electric conductivity were found consistent with the reported results, 20,29,30 which may be attributed to the damping out of successive relaxation modes in the lattice. 31 The Curie point indicates the transition temperature where the material observes paraelectric to ferroelectric transition.…”

Ceramic pellets of (Ba1-xCax)(Zr1-yTiy)O3, (x = 0.140 to 0.160, y = 0.9), were prepared via solid- state reaction method followed by double sintering. Dielectric properties (ε, tan δ, and σ) of the prepared compositions were measured, in the temperature range from room temperature (RT) to 450°C, at various frequencies (12- 1000 kHz). The dielectric measurements show a single phase transition, at around 100°C, for the prepared (Ba1-xCax)(Zr1-yTiy)O3 (BCZT) compositions, in the measured temperature range. The structural variation was studied using high temperature X- ray diffraction (HT- XRD) measurements of the compositions with x = 0.150 and 0.155. The HT- XRD results were found consistent with the dielectric measurements, showing structural anomaly at around 100°C; showing tetragonal phase, between RT and around 100°C; and cubic phase, above 100°C, in the measured temperature range.
