Abstract

Nano - BaTiO3 powders were synthesized using the hydrothermal method. During the synthesis, titanium isopropoxide, isopropanol and barium acetate were used as the main raw materials. The suspension reacted hydrothermally in a teflon vessel at 200 ºC in1 h. These modified BaTiO3 powders were characterized by several different methods; FT - IR, XRD, BET, SEM and thermogravimetric analysis and differential thermal analysis (Tg - DTA) . The phase purity and crystalline structure of BaTiO3 was determined using an X - ray diffractometer (XRD) with Cu Kα radiation. According to the X-ray diffraction analysis, BaTiO3 nano powders have cubic BaTiO3 phases at room temperature. The SEM results revealed that the morphologies and the sizes of the synthesized BaTiO3 particles hadan accelerating voltage of 20 kV. The particle size of BaTiO3 was calculated as 18.97 nm (for the λ = 1.54056 Å ), using the Schreer equation. The average pore diameter was measured using BET analysis and the pore size was found to be 33.6424 nm.
