摘要：

Nd3+ doped PbZr0.52Ti0.48O3 (PNZT) nanopowders were prepared by sol-gel methods in Ethylene glycol system. Neodymium nitrate was used as Nd3+ source. The reaction mechanisms of nanopowder preparing process from the Sol were discussed through using FTIR, XRD, TG-DTA, and it was proved that the beating temperature of PNZT was 50 degrees C-100 degrees C higher than PZT. PNZT lattice structure was characterized by XRD, Raman, SEM and TEM. Results show that the lattice aberrance of PNZT was increased with Nd3+ doping. Comparing with PZT, the constant a and V of PNZT were decreasing with the addition of Nd3+, but the c and c/a were increasing with a few Nd3+ doping and then were decreasing gradually with the addition of Nd3+. If Nd3+%<= 9% (mol), perovskite PNZT nanopowders which particle size is about 20-50nm could be formed. Nd3+ replaced Pb2+ of PZT and formed steady perovskite crystal with Ti4+ and O2-.
