Hydrothermal Synthesis Nano-SrTiO3 Powder and the Factors Control

Article Preview

Abstract:

In this research, SrTiO3 powder is prepared by hydrothermal synthesis method. In the process of reaction, SrCl2 and Ti (OC4H9) 4 with NaOH can obtain the precursor as reactants and mineralizer respectively. Then take the precursor into autoclave without any pretreatment, to make it react under the temperature of 150 °C and the stirring speed 360 r/min in 8 hours. After the reaction finishing, the prepared SrTiO3 powder were charactered by X-ray diffraction and SEM. the results of experiment showed that we succeed in making nanostrontium titanate powder under above condition and the grain size is almost 60 nm.
