“…All these classes are formed of dielectric materials. Ferroelectric materials are dielectric materials with spontaneous polarization that can be reversed by an external electric field and retain polarization when removed [2][3] [4]. Due to its high dielectric constant, low dissipation factor, adjustable dielectric constant at different frequencies, and low leakage current, barium strontium, titanate is a ferroelectric material now receiving much attention [5] [6].…”

The sol-gel process was utilized in the production of the ferroelectric material Ba0.7Sr0.3TiO3. Barium and strontium acetate were employed as sources for Ba and Sr, respectively, and Ti(IV) isopropoxide was used as a source for Ti. The acetic acid was utilized as a solvent for Ba and Sr acetate, whereas 2-methoxy ethanol was used as a stabilizer for Ti (IV) isopropoxide. The effect of high temperatures on electrical and structural were studied. The FESEM revealed the particle size of all samples with different temperatures. The XRD shows the Ba0.7Sr0.3TiO3 samples have a tetragonal phase for all temperatures (1000, 1100, 1200˚C). The high temperatures impacted tetragonality and the lattice constant (a, c); the lattice constant decreased at higher temperatures. The ferroelectric sample sintered at 1000 degrees Celsius had dielectric characteristics that were inferior to those of the Ba0.7Sr0.3TiO3sample sintered at 1100 and 1200ºC degrees Celsius. When the dielectric constant was graphed as a function of temperature, the Curie temperature appeared to be between (28-32) degrees Celsius.

The effect of ion radius on the structural and electrical properties of the perovskite oxide Ba1-x SrxTiO3 thin film is investigated in this work. X-ray diffraction analysis confirmed the formation of phase perovskite structures. Investigations of ceramic microstructures and mechanical properties showed their dependence on the value of ratio x. X-ray diffraction (XRD) and Field emission scanning electron microscopy (FESEM) are used to study the crystallographic aspects of the materials. The XRD pattern changed from tetragonal to cubic as x rose. FESEM images revealed the particle size varied with the values of x increased. The results show that as the ion radius varies, the crystal structure undergoes distortions, affecting the symmetry and stability of the BaSrTiO3 thin films. Electrical properties change depending on the change in particle size.
