| Abstract: | Pb(Ti0.48Zr0.52)O3 minicrystal was synthesized by the hydrothermal method,using TiO2 powder,Pb(NO3)2,ZrOCl2·8H2O,and mineralized by KOH.The effects of reaction temperature,KOH concentration,reaction time,Pb/(Zr+Ti),raw material concentration,and mineralizer type on the hydrothermal process for preparing Pb(Ti0.48Zr0.52)O3 minicrystal were investigated.The best technique parameters were determined.As-prepared Pb(Ti0.48Zr0.52)O3 minicrystals were characterized using XRD and SEM.Our results indicate that uniformly distributed Pb(Ti0.48Zr0.52)O3 minicrystal with little coalescence can be synthesized using the above method,the grain diameter range is 0.5～1.0 μm. |
