摘要：

Conditions for formation of perovskite Pb(Zr0.52Ti0.48)O-3 phase by the hydrothermal synthesis are investigated. Pb(Zr0.52Ti0.48)O-3 ceramics were synthesized by hydrothermal process above 180 degrees C for 2 h reaction using 5 similar to 30 M KOH solution as a mineralizer. Particle size increases in proportion to the mineralizer concentration. As a result of EDX analysis, PZT powders synthesized using 50 M of KOH as a mineralizer were considered as 2.42 mol% K doped-PZT powders. And 2.42 mol% K doped-PZT has much higher mechanical quality factor than undoped PZT ceramics. The sintering properties showed 7.987 g/cm(3) of sintered density and 3-4 um of grain size.
