Barium Titanate (BaTiO3) Nanoparticles

Barium titanate (BaTiO₃) nanoparticles have widely been investigated to be used as a material for dynamic random-access memories, electro-optic devices, multilayer ceramic capacitors (MLCC). These applications originate from barium titanate nanoparticles high dielectric constant and ferroelectric property. Barium titanate nanoparticles are regarded as desirable nanoscale materials in the today trend of manufacturing miniaturized electronic devices. Through employing barium titanate nanoparticles, the thickness of the ceramic layers as well as particle size are obtained in favorable conditions to be applied in multilayer ceramic capacitors (MLCC) fabrication. Additionally, the ceramics produced using the non-agglomerated nanoscale barium titanate with practically narrow size distribution appear to show unique compaction and consolidation properties. The finite size impact on the ferroelectricity in nanomaterials is another good reason to try to obtain barium nanoparticles. The synthesis methods of barium nanoparticles comprise wet-chemical processing, the traditional solid-state reaction and homogeneous precipitation. In order to synthesize pure crystalline nanoscale barium titanate, a calcination process at temperatures over 700˚C is essential in all the methods mentioned above.
