• Nano-sized BaTiO3 particles were prepared at 90°C using TiO2 and Ba(OH)2 as precursors by microwave-assisted (M-A) heating and conventional-heating (C-H) processes. Compared to the formation of BaTiO3 particles using the C-H process, the M-A process led to increased rate of formation by about 6 times. BaTiO3 particles of 29 nm in average particle size were obtained after treatment for 15 min by using microwaves during the heating process at 90°C. The use of microwaves led to the formation of smaller sized particles with narrower particle size distribution compared to that of C-H process.
