We developed a hydrothermal synthesis method for lead-free perovskite (Bi1/2K1/2)(ZrxTi1-x)O3 (BKZT) powders. Singlephase BKZT powders with various nominal Zr contents as high as x = 0.10 were obtained using amorphous hydrous oxide (ZrxTi1-x)O2nH2O precursors prepared by the hydrolysis of Zr- and Ti-alkoxides, whereas a reaction using a mixture of crystalline TiO2 and ZrO2 powders did not provide single-phase BKZT. Elemental analysis revealed that the Zr contents of the obtained BKZT powders were slightly higher than the nominal values. The powders had fine particle sizes smaller than 300nm and were stable against a higherature heat treatment at 1000C. These observations suggest that the hydrothermally derived powders are suitable for use in fabricating bulk BKZT ceramics via sintering.
