The Novel Formation of Barium Titanate Nanodendrites

Abstract

The barium titanate (BaTiO3) nanoparticles with novel dendrite-like structures have been successfully fabricated via a simple coprecipitation method, the so-called BaTiO3nanodendrites (BTNDs). This method was remarkable, fast, simple, and scalable. The growth solution is prepared by barium chloride (BaCl2), titanium tetrachloride (TiCl4), and oxalic acid. The shape and size of BaTiO3depend on the amount of added BaCl2solvent. To investigate the influence of amount of BaCl2on BTNDs, the amount of BaCl2was varied in the range from 3 to 6 mL. The role of BaCl2is found to have remarkable influence on the morphology, crystallite size, and formation of dendrite-like structures. The thickness and length of the central stem of BTND were ~300 nm and ~20 μm, respectively. The branchings were found to occur at irregular intervals along the main stem. Besides, the formation mechanism of BTND is proposed and discussed.

Advances in the synthesis, characterizations and applications of barium titanate. A review

“…Ulfa et al studied how temperature and time holding affected the dielectric characteristics of barium titanate using the coprecipitation process, which was then characterised using x-ray diffraction, and scanning electron microscopy was, barium titanate was found to have a perovskite structure in its ideal single phase, (Ulfa et al, 2020). A novel formation of barium titanate Nano dendrites was investigated by C. Huang et al, (2014) using co-precipitation, the addition of BaCl2 solvent is a factor to the shape and size of BaTiO3, also BaCl2 has an effect on crystalline size, morphology and emergence of dendrite-like structures. (C. Huang et al, 2014).…”

(C. Huang et al, 2014). Solid-state reaction and co-precipitation methods was used to detect the consequence of powder preparation on the PTCR characteristics of barium titanate, it was concluded that coprecipitation process produce a greater PTCR features and superior repeatability of prepared samples and low temperature resistance, (Chatterjee, n.d.).…”
