Effect of BaTiO3 size on dielectric property of BaTiO3/PVDF composites

Journal of Electroceramics, 2007
The BaTiO3/polyvinylidene fluoride (BaTiO3/PVDF) polymer-based composites with different size and concentration of BaTiO3 particles were fabricated via a simple physical mixing and subsequently hot-press processing. Effect of the filler size and frequency on the dielectric properties of the BaTiO3/PVDF binary composites was discussed.

Heating effect of BaTiO3 in microwave field and microstructure of BaTiO3

Science in China Series A: Mathematics, 1997
Microwave equipment at 2 450 MHz was employed to prepare BaTiO3. The heating effect of the system in the microwave field, which was influenced by several factors including dielectric properties of synthesis system and thermal insulate structures, was discussed in detail. The heating rates of the synthesis system were mainly determined by BaCO3 and TiO2

Phase transitions in BaTiO3 thin films and BaTiO3/BaZrO3 superlattices

Journal of Applied Physics, 2014
Using pulsed laser deposition, we grew a ferroelectric [BaTiO3]Λ/2/[BaZrO3]Λ/2 (BT/BZ) superlattice with a stacking periodicity of Λ = 256 Å and a BT single film on a La1/2Sr1/2CoO3-buffered (001)MgO substrate, and then studied the phase transitions of these materials.
