Abstract

Nano-sized cubic BaTiO 3 was prepared rapidly at 90 °C using TiO 2 and Ba(OH) 2 as precursors by a home-built semi-continuous microwave-assisted synthesis system. Cubic BaTiO 3 particles of 30 to 50 nm were obtained after treatment for 5 min at 90 °C. The conversion of TiO 2 to BaTiO 3 reached 100% after 15 min. The approximate total energy consumption of microwave irradiation during reaction at 90 °C for 5 min was 118 kJ which was lower than that used by conventional heating (792 kJ) with an oven at 90 °C for 5 min.
