Abstract
We have been studying the synthesis of nano sized particles using hydrothermal treatment, and developed various kinds of oxided particles such as aluminum oxide, cerium oxide, zirconium oxide, indium tin oxide and barium titanate and so on. Characteristics of synthesized particles are as follows. (1) Particle size is controlled in the range of about 10 to100 nm by changing the condition of precipitation of hydroxides and hydrothermal treatment. (2) Particles have plate like shape. (3) The synthesis is applied to various kinds of complex oxided particles. (4) Each particles shows crystal structure standing comprison with balk materials. We report detailed synthetic methods and the characteristics such as particle shape using high resolution TEM and analysis of crystal structure.
