Nanocrystalline Pb(Zr0.52Ti0.48)O3 was prepared from lead acetate, zirconium oxynitrate and tetrabutyltitanate by a sol-gel method. It is found that both the crystallization temperature of precursor PZT and PZT product size were increased with increase of V(C3H8O2)/V(H2O) ratio in solution used. At V(C3H8O2)/V(H2O)=4.47 the gel was formed moderately quick, and the nanocrystalline PZT with uniform granularity and low crystallization temperature could be obtained. The diameter of the final nanocrystalline was ranged in 60~70 nm as measured by atomic force microscopy(AFM). The crystallization temperature of the precursor PZT was 443℃ and the crystallization reaction was completed at 500℃ by DTA and TG. The sol-gel reaction process was monitored by FT-IR and XRD.
