The (Na0.8K0.2)0.5Bi0.5TiO3 perovskite-type solid solution was prepared under mild condition at 160°C using Ti(OC4H9)4, Bi(NO3)3•5H2O as Bi and Ti sources by a mechanical hydrothermal method. It is suggested that mineralizer plays an important role in facilitating the crystallization of obtained products and promoting the formation of perovskite phase. The crystallized products were characterized by means of XRD, SEM and DSC-TG. The results show that the well-developed crystallite with a pure pervoskite structure has been formed. The powders with regular cubic morphology exhibit low agglomeration and narrow particles size distribution in the range of 3~6μm.
