Hydrothermal conditions for the formation of tetragonal BaTiO3 particles from potassium titanate and barium salt

Review on Sol-Gel Synthesis of Perovskite and Oxide Nanomaterials

“…In general, the process uses titanium alkoxide and Ba (or Sr) salts, with and without occurrence of organic species. The reaction modifies and stabilize cations agents preventing the accumulation of the particles [ 35 , 36 ]. The main advantages of this method are: low working temperatures, large control of the particle size (from 10 to 100 nm) and the possibility of synthesize mixed oxide networks.…”

Recent development on modification of synthesized barium titanate (BaTiO3) and polymer/BaTiO3 dielectric composites

“…Generally, the appearance of BaTiO3 is white powder. [6] However, when large crystals are formed, BaTiO3 becomes transparent. [7] BaTiO3 has the advantage of high dielectric constant and replaces lead zirconate titanate in the field of piezoelectric sensors, capacitors and high power energy storage devices.…”

“…[167] For the simplest parallel plate capacitors, the electric energy after charging can be expressed in equation (5). Therefore, the variation of electric energy after deformation of dielectric elastomers under external force can be calculated by equation (6). [168]…”

Synthesis of BaTiO3nanoparticles as shape modified filler for high dielectric constant ceramic–polymer composite

“…[17][18][19][20] BT was synthesized by the hydrothermal method, which allows for synthesis in various particle forms, for example, spherical shape, coral-like shape and rod-like shape. [21][22][23] In particular, spherical BT have been used in many studies for composites with high dielectric constants, and in the case of rod-like shape BT, many studies have investigated the aspect ratio which affects the dielectric constant. 24,25 On the other hand, few studies have investigated composites of BT in the coral-like form, 26 and the dielectric properties of BT dispersed in PDMS elastomer have rarely been reported.…”
