“…22,34 Green chemistry is the procedures and chemical products that reduce or eliminate the creation of harmful or hazardous by-products. [35][36][37] Green chemistry prevents molecular contamination and pollution, causing source reduction. 35 However, the size effect in ferroelectrics can be attributed to various parameters.…”

Ferroelectric materials differ from other dielectrics because their polarization stays after removing the external field. Hysteresis loops describe a wide range of behavior in engineering, chemistry, and physics disciplines. Sol-gel has prepared barium strontium titanate (Ba0.7Sr0.3TiO3; BST) nanocrystalline ceramics. Ba1-xSrxTiO3 crystal size increased as the sintering temperatures elevated from 900 °C to 1200 °C. The XRD patterns of Ba0.7Sr0.3TiO3 exhibited a tetragonal phase. (FESEM) used to measure the average particle size. The relationships between crystal size, dielectric and ferroelectric properties were investigated, showing better dielectric and piezoelectric parameters with increasing crystal and particle size. The increasing particle size also slightly shifted the curie transition temperature towards higher temperatures. The coercive field of Ba0.7Sr0.3TiO3 goes down as the crystal size increases, but the remnant and spontaneous polarization get better. This material is advantageous for applications in tunable capacitor devices.

Cerium oxide, also known as CeO2, can be synthesized by the hydrothermal process with cerium nitrate precursor solution. After drying and sintering at 800,900, and 1100 C, different-sized cerium oxide nanoparticles were produced from the solution. Using x-ray diffractometers, the researchers were able to determine that all of the cerium oxide nanoparticles have a unique structure called fluorite crystalline structures. The structural, morphological and optical properties of films were investigated by a set of characterization techniques such as X-ray diffraction (XRD) and scanning electron microscopy (SEM). The estimation of crystallite size is (22.12,27.34 and 42.02 nm), which is confirmed by Scherrer formulae from XRD pattern. The dielectric constant increased with the increase of crystallite size due to the size effect. The crystal size increased with increased sintering temperature. Keywords: Cerium oxide (CeO2), structural, crystal size, , morphology,Dielectric constant.
