Ơn Đỗ V, Anh Đỗ P, Thịnh NV, Tùng VT, Chương TV. Influence of Ba/Ti molar ratio on characteristics of BaTiO3 nanoparticles synthesized with hydrothermal method. hueuni-jns [Internet]. 2021Mar.10 [cited 2021Apr.21];130(1A):23-9. Available from:


Highly dispersed BaTiO3 nanospheres with a uniform particle size were synthesized with the hydrothermal method. The influence of Ba/Ti molar ratios on the formation of BaTiO3 nanospheres was studied by analyzing the XRD and SEM data. The TiO2·H2O synthesized with the sulfuric acid method assisted by ultrasonication was used as a starting material. Highly dispersed BaTiO3 nanospheres with an average size of about 100 nm were obtained at 200 °C in 12 hours with a Ba/Ti ratio of 1.5. The Ba/Ti ratios have a strong influence on the formation of nano BaTiO3 and the phase transition. The particle size increases with the Ba/Ti ratio, while the uniformity decreases.
