Preparation of PZT95/5 Nano-powders with Modified Sol-Gel Method

PbZr0.95Ti0.05O3 nano-powders were synthesized with a modified sol-gel method at low calcining temperatures. Pb(CH3COO)2.3H2O, Zr(NO3)4.5H2O and Ti(C4H9O)4 were used as parent reagents. The sol-gel method was modified by cutting down certain procedures and calcining wet gel in a proper heating sequence. XRD and TEM testy show that the PZT nano-particles are ultrafine and uniform, their diameters are around 10 nanometers.
