Abstract
This work investigated the effect of polyethylene glycol (PEG) as an additive on barium titanate (BaTiO3, BT) nanoparticles (NPs) synthesised by a hydrothermal process. The structure, morphology, dispersion and crystallinity of BT NPs were tested by differential scanning calorimetry–thermogravimetric analysis, X-ray diffraction, field emission scanning electron microscope, transmission electron microscope and Raman spectroscopy, respectively. The results showed that the main phase of BT NPs includes the cubic BT phase with a tiny tetragonal phase. Also, the addition of PEG with different concentrations has a very positive effect on the control of the grain size and grain shape of the samples during the hydrothermal process. When the concentration of PEG is 1 g/l, BT NPs possess the best morphologies and highest dispersibility, and the average size is about 71.86 nm.
