Abstract: Ion exchange of Ba to Sr was carried out for spherical BaTiO3 particles (particle size of 600 to 700 nm) by hydrothermal method using strontium nitrate aqueous solution, and the hydrothermal conditions were at 200 °C for 0.5 to 1.5 mol/L for 24 h. After hydrothermal treatment, all samples remained the form and particle size of the source materials. The Sr substituted BaTiO3 sample obtained by hydrothermal treatment with strontium nitrate at 1.5 mol/L showed the composition of Sr0.14Ba0.86TiO3 by elemental analysis by EDX, and the Curie temperature was confirmed to be 90 °C by Raman spectra, respectively.
