“…The characterization of the dielectric behavior is important not only for the theory of the polarization mechanism, but also from a practical perspective, it is important to understand the frequency dependence of the dielectric constant. The dielectric constant of a material determines its ability to store electrostatic energy [9].…”

Dielectric materials used in electrical energy storage devices, must have a high dielectric constant with low dielectric losses. In this work, new method was used to improve the dielectric properties of 3Y-TZP (3% mol yttria tetragonal zirconia polycrystalline) ceramics, by adding different percentages of nano barium titanate (BaTiO3) to glaze mixture. 3Y-TZP specimens were sintered at a 1450 o C, and the glaze layer was fired at 800 °C. BaTiO3 increased from 40 wt% to 60% resulting an increase in the crystalline size. As well, both dislocation density and lattice strain were decreased down to 175×10 8 lines / mm 2 and 12×10-3 , respectively. The dielectric constant values were doubled up to 75.6 for glass-coated specimens when adding 60 wt% BaTiO3. This increase was accompanied by an increase in tangent losses value up to 0.026. Electrical breakdown Ebr of specimens was measured with the number of repeat breakdown and at different ramp rate of the voltage RRV. The Ebrmax is 55.7 kV / mm at RRV 5 kV / s for coated specimens without BaTiO3. A drop in Ebr has reached a minimum value of 41.7 kV/s at the same RRV. Various phenomena accompanied the Ebr, including electromechanical, electrothermal and electrical treeing.

Solution combustion synthesis (SCS) has been widely used to produce simple and complex oxides with a desired morphology (size and shape). SCS is valuable due to low cost, simplicity and energy efficient synthesis. To guarantee the best molecular‐level mixing of reactants in an aqueous or solvent‐based solution some parameters need to be controlled, such as fuel type, metal cations precursors, stoichiometry ratio (φ), pH effect, atmosphere and initiation type. These determine the final properties of the oxide materials, providing the potential to reach different morphologies, which are essential for their final applications. This Review article focuses on the crucial parameters in SCS and how these affect the overall materials properties from nanostructures to thin films. To finalize, special attention is given to the application of SCS to form metal oxide thin films at low temperature and their application in thin film transistors (TFTs).
