Barium Titanate (BaTiO3 or BT) is one of which the most attractive ferroelectric materials that have been widely studied. The fabrication process affects the properties of ferroelectric materials where increasing the sintering temperature is one of the ways to improve their performance. In this study, BT has been synthesized using the co-precipitation technique. The samples were sintered for 4 h with varying sintering temperatures of 700°C and 800°C. The purpose of this study was to investigate the effects of variation of sintering temperatures on the microstructure, dielectric constant, and chemical bonds of BT. The micro structure observed by the X-Ray Diffraction (XRD) showed that the crystal size of the sample at 800°C was larger than the sample at 700°C. Furthermore, the Fourier Transform Infrared (FTIR) analysis revealed that increasing the sintering temperature decreased the intensity of the impurities’ peaks of C-H and C=O atomic bonds in the BT structure. The impurity that appear is the carbonate phase which does not decompose during the formation of BT. Moreover, based on the Resistance Capacitance Inductance (RCL Meter) examination, increasing the sintering temperatures could enhance the dielectric constant of the BT samples from 65 to 162. Thus, it can be inferred, that the increase in the sintering temperature could improve the crystal structure and decrease the impurities phases of the BT materials so that further could enhance the dielectric constant.

“…Glucose, as a common carbon source, was used as an aggregation inhibitor to confirm the effect of freeze-drying and aggregation inhibitor on the size and dispersion of the BTO NPs. MA is more cost-effective than other precipitants like Oxalic acid (OA) and Tartaric acid (TA). − The reducing agent NaOH used in this work is also nearly 3 times cheaper as compared with NH 4 OH used for the synthesis of BTO NPs elsewhere. ,, We have systematically investigated the effect of different synthetic conditions on the quality of the BTO NPs. It is found that with freeze-drying, highly pure tetragonal BTO NPs with a size distribution of ∼170 nm can be obtained.…”

“…9,10 For example, in multilayer ceramic capacitor (MLCC), a minimum of five grains per layer (layer thickness <0.6 μm) is generally the case, 11 which further requires the BTO NPs with ∼100 nm size and a higher tetragonality of above 1.0080 to achieve a higher dielectric constant. 12 Endeavors have been paid to synthesize narrowly dispersed BTO NPs with high-purity, controllable particle size, and uniform size distribution. 3,13−15 Generally, the morphology, particle size, poly-morphism, and phase compositions directly rely upon the synthetic route.…”

“…Progress has been made in obtaining BTO NPs with size below 200 nm by the CP method. 12,21 However, it is currently challenging for the CP method to further scale down the size below 100 nm. Nano-scale synthesis is generally followed by obvious aggregation, which limits the quality of the slurry in the fabrication process of the multilayer chip.…”

The miniaturization and demand for high-performance BaTiO 3 (BTO)-based multilayer chips have evoked tremendous research to further scale down the size of the BTO nano-particles (NPs) by wet chemical techniques. However, synthesizing narrowly dispersed tetragonal-BTO NPs with nano-scale size is still challenging. In this work, a maleic acid-assisted modified coprecipitation (CP) route armed with freeze-drying was carried out to obtain BTO NPs with a mean size of ∼170 nm and a high c/a ratio of 1.0109. In addition, the synergetic effect of freeze-drying accompanied by glucose as an aggregation inhibitor resulted in ultra-fine (∼44 nm) narrowly dispersed tetragonal BTO, which to the best of our knowledge is the finest compared with those obtained by CP methods and even hydrothermal method. The maximum permittivity of >12,000 with low dielectric loss (0.03) can be obtained for the asobtained BTO-Fr-Gl-pH9-1400C ceramic pellet. This modified synthetic strategy and the obtained powder are promising for further scaling the BTO-based multilayer chips.

Considering the multifunctional performance, the (Ba0.7Sr0.3)0.98Ca0.02Ti1−xCoxO3 (x = 0.00–0.2) ceramics are successfully synthesized using the traditional solid‐phase reaction method. The effect of cobalt doping on the samples’ structural, morphological, magnetic, electrical, and optical characteristics is elucidated. Raman spectroscopy and X‐ray diffraction data confirm the dopants’ integration into the cubic perovskite microstructure. At room temperature, the magnetization–magnetic field intensity hysteresis loops from vibrating sample magnetometer reveal the samples’ ferromagnetic character, with a maximum magnetization of 0.091 emu g−1 achieved for x = 15%. The real part of the initial permeability demonstrates that the replacement of Co2+ causes a shift in resonance toward higher frequencies above 85 MHz, indicating the potential of the synthesized ceramics for high‐frequency magnetic applications. The variation in dielectric characteristics from 100 Hz to 10 MHz is explained using electron hopping on octahedral sites and Maxwell–Wagner's model. The increase of AC conductivity in the high‐frequency region is consistent with the strengthening of the grain effect on the conduction mechanism, which supports the small‐range polaron‐hopping theory. The complex electric modulus's peak (M′′) shifts toward a higher‐frequency region with cobalt content, suggesting a reduction in the relaxation rate. The optical bandgap is observed to decrease from 3.08 to 2.96 eV with cobalt content.
