摘　　要：以醋酸铅、硝酸锆、钛酸丁酯为原料,改进溶胶-凝胶法,制备得到锆钛酸铅95/5纳米粉体.改进溶胶-凝胶法省去溶胶加水、凝胶干燥、干凝胶研磨等步骤,采用加热蒸馏溶胶制备凝胶,蒸馏回收溶剂并干燥凝胶,凝胶分段加热处理等方法,简化了加工工艺,大大缩短了合成周期,降低了成本.XRD和TEM分析表明,用改进sol-gel法制备得到的PZT粉体煅烧温度低、晶粒细小、均匀,直径约10nm.PbZr0.95Ti0.05O3 nano-powders were synthesized with a modified sol-gel method at low calcining temperatures. Pb(CH3COO)(2).3H(2)O, Zr(NO3)(4).5H(2)O 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 tests show that the PZT nano-particles are ultrafine and uniform, their diameters are around 10 nanometers.
