Hydrothermal synthesis and characterization of Bi4Ti3O12

A pure phase bismuth titanate, Bi4Ti3O12, has been prepared by hydrothermal synthesis. This powder product shows yellowish gray color and plant form shape. Factors that influence the formation of Bi4Ti3O12 include the content of mineralizer KOH, the molar ratio of Bi/Ti, reaction time and temperature. Compared to the solid state reaction for Bi4Ti3O12, current hydrothermal synthesis is preferable in terms of low reaction temperature, homogenous particle distribution and short reaction time.
