“…This addition is effective for reducing the Curie temperature from 120 to 40-60°C. Thus, CaZrO 3 behaves as a suppressor of Curie temperature [43]. In case of addition of 1 mol% BiNbO 4 in BaTiO 3 , Curie temperature is increased to 140°C whereas the dielectric is decreased remarkably.…”

The recent developments of energy storage devices are concerned with larger energy storage ability, low loss and good temperature stability. It has a great technological importance in engineering science. The dielectric materials like ceramics and glass ceramics have great interest in electronic ceramic industry due to above concern. The ceramic dielectrics are used as a capacitive element in electronic circuits. The perovskite glass ceramics have very high dielectric constant and low dielectric loss. The high dielectric constant in glass ceramics is attributed to space charge polarization. In order to produce glass ceramics of high dielectric constant, barium titanate glass ceramics is the first discovered ferroelectric perovskite. In this review article, we are summarizing the dielectric behavior of perovskite glass ceramics such as

The influences of CaZrO 3 on the dielectric properties and microstructures of BaTiO 3 (BT)-based ceramics have been investigated. The experiment results showed that the dielectric constant at room temperature increased with the addition of CaZrO 3 in the range of 0-3.0 mol%, which could be explained by the growth of BT grains. XRD analysis revealed that the tetragonality declined as CaZrO 3 concentration increased. XRD patterns of BT ceramics with different amounts of CaZrO 3 doping were analyzed by a recently developed procedure-materials analysis using diffraction (MAUD), which was based on the Rietveld method combined with Fourier analysis. The results depicted that the high temperature peak of temperature-capacitance characteristics (TCC) was largely dependent on the micro-strain of samples. Furthermore, more CaZrO 3 doping resulted in lower porosity and higher density. It was revealed that proper usage of CaZrO 3 could improve the dielectric properties significantly, which was benefit to develop X8R multi-layer ceramic capacitors.
