Improving Dielectric Properties of PVDF Composites by Employing Surface Modified Strong Polarized BaTiO3 Particles Derived by Molten Salt Method

“…The molten salt synthesis (MSS) method is one of the simplest, most versatile, and highly cost-effective methodology to prepare crystalline, chemically pure, single-phase oxides nanostructures. , Although the MSS method has been applied to build bulk materials for a long time, the preparation of uniform oxide nanostructures using this technique has only arisen within the current century. , Many research groups, including our laboratory, have applied this generalized methodology to the fabrication of various single-crystalline perovskite oxide nanostructures. Examples have been presented for preparing BaTiO 3 nanowires, , BaTiO 3 nanostrips, BaZrO 3 nanospheres, (K 0.5 Bi 0.5 )­TiO 3 nanowires, (La, Bi)­AlO 3 nanoplates, and more. Previous works suggested that the calcination temperature is an important andreadily controllable factor that influences the size, as well as the crystallinity of the as-prepared particles, because the viscosity in the molten growth medium decreases when the temperature increases, which has an effect on the initial nucleation and subsequent diffusion of the growth species.…”

Synthesis and characterization of SmAlO3 by stearic acid route

“…Especially, the SmAlO 3 ceramics prepared by the solid state reaction route require very high calcination and sintering temperatures of about 1400 ℃ and 1650 ℃ to densify, respectively [11]. Recently, tremendous efforts have been devoted to enhancing the sintering performance of ceramics, and a variety of synthesis approaches have been carried out, such as co-precipitation method, molten salt synthesis, hydrothermal synthesis, sol-gel route, and polymer complex method [12][13][14][15][16][17]. In the chelating sol-gel route, which is commonly used to prepare a variety of nanometer complex oxides, many metal ions are inclined to generate precipitation due to their strong hydrolysis ability in aqueous solution, and thus lead to their inhomogeneous dispersion.…”

Chemical synthesis of SmAlO3 by stearic acid route: structure, morphology and microwave dielectric properties

“…Especially, SmAlO 3 ceramics prepared by solid state reaction route require very high calcination and sintering temperatures of about 1400 o C and 1650 o C to be densified, respectively [11]. Recently, tremendous efforts have been devoted to enhancing the sintering performance and a variety of synthesis approaches have been carried out, such as co-precipitation method, molten salt synthesis, hydrothermal synthesis, sol-gel route and polymer complex method [12][13][14][15][16][17]. These wet-chemistry methods show several advantages like lower synthesis temperature, shorter reaction time and finer grain size, which influence the sintering and dielectric properties positively.…”
