Mn1-xNixFe2O4 nanoparticles were successfully synthesized using co-precipitation method with various Ni concentrations. The crystal structures and dielectric properties of nanoparticles were analyzed for different Ni concentrations. The crystallite size of nanoparticles decreased from 19.7 to 3.6 nm with the increase of Ni concentration from 0.3 to 0.8. The dielectric properties were studied at frequencies of 10 -1000 kHz. The dielectric permittivity (real and imaginary) decreased with the increase of frequency up to 200 kHz. The highest real dielectric permittivity (ε') was 343.3 and the imaginary dielectric permittivity (ε") was 440.5, for Ni concentration of 0.5 at frequency 10 kHz. Furthermore, the dielectric permittivity of the Mn1-xNixFe2O4 nanoparticles were dependent on the frequency. This type of behavior can be explained by the Maxwell-Wagner model.

“…If a material has a greater number of grain boundaries, then the value of k becomes high in the range of frequency, where interfacial polarization is active, as grain boundaries trap the charge carriers at the interfaces and do not allow them to move. Hence, they enhance the polarization and ultimately give rise to an increased value of dielectric constant at low frequencies [67].…”

Energy storage devices constitute one of the research areas in recent years. Capacitors are commonly used for the storage of electrical energy. The current research is focusing on not only the improvement in energy density but also the materials which are environment friendly. Polymer composites are known to be technically essential materials owing to their wide range of applications. Enormous research has been devoted to zinc oxide- (ZnO-) based polymer nanocomposites, due to their extraordinary dielectric properties. This review article presents a detailed study of the dielectric properties of ZnO-based nanocomposites. The dielectric constant study includes the effect of transition metals and rare earth metals as a dopant in ZnO. This review gives an insight into the mechanism responsible for the variation of dielectric constant in ZnO nanocomposites due to various factors like size of nanoparticles, thickness of the thin film, operating frequency, doping concentration, and atomic number. The observations have been summarized to convey the mechanism and structural changes involved in the ZnO nanocomposites to the researchers. The deployment of biodegradable nanocomposite materials is expected to open an innovative way for their outstanding electronic applications as storage materials.

“…The Ba0.6Sr0.4TiO3 with cubic structure increased the dielectric properties of the material Ba0.6Sr0.4TiO3 produced [12], [17], [33]. Besides the crystal structure, the dielectric properties of the Ba0.6Sr0.4TiO3 material are also influenced by the crystal size, where the dielectric property increases with the crystallite size [12], [29], [34]. In this study, the sintering temperature of 1100 °C produces Ba0.6Sr0.4TiO3 material with the best physical properties because it has a cubic-shaped crystal system and the largest crystal size.…”

Barium Strontium Titanate (BST) ceramic materials are widely used in electronic devices due to their stable operation at high temperatures, high tunability, low tangent loss, low DC leakage, and alterable curie temperatures. While pure BST materials are usually produced at high sintering temperatures (1250 °C), there are limited studies on the temperature and duration of the sintering process to produce pure BST, synthesised from micro or even nano-sized raw materials. This study aims to determine the effective sintering temperature for producing pure BST material using a mixture of raw materials with a mean particle size of 0.4 μm after milled for 58 hours. The BaCO3, SrCO3, and TiO2 materials as raw materials for Ba0.6Sr0.4TiO3 synthesis were milled for 58 hours to produce a homogeneous mixture with a mean particle size of 0.4 μm. Sintering was carried out in a temperature range of 500-1100 °C for 1 hour. This study investigates the impact of sintering temperature on the physical properties and the purity of Ba0.6Sr0.4TiO3 powder using the x-ray diffraction method. The results showed that the Ba0.6Sr0.4TiO3 phase was formed at a sintering temperature of 700 °C. Pure BST material was formed at the sintering temperature of 1000 °C with a crystallite size of 41 nm. Whereas at a higher sintering temperature (1100 °C), the pure BST material formed produced a larger crystallite, sized at 43 nm with cubic structure. The synthesis temperature and duration recorded in this research are lower than recorded in the BST material preparation using the solid-state method. The results of this study indicate that the sintering temperature greatly affects the purity, crystal system and crystallite size of the Ba0.6Sr0.4TiO3 material produced. The sintering temperature of 1100 °C produces Ba0.6Sr0.4TiO3 material with the best physical properties because it has a cubic-shaped crystal system and the largest crystal size.
