【摘要】 以Pb(NO3)2、ZrOCl2.8H2O和TiCl4作为原料,NaOH作为矿化剂,水热合成锆钛酸铅粉体。系统研究了物质的量比Pb/(Zr,Ti)、矿化剂NaOH浓度、反应温度、反应时间4个因素对PZT晶相形成和粉体形貌的影响。结果表明Pb/(Zr,Ti)在1.7～2.0,NaOH的浓度为1mol/L、反应温度为200℃、时间2h的水热条件下,可以合成结晶良好的Pb(Zr,Ti)O3粉末。更多还原

【Abstract】 Lead zirconate titanate(PZT) powders were hydrothermally synthesized by using the Pb(NO3)2,ZrOCl2·8H2O and TiCl4 as raw materials.The effects of Pb/(Zr,Ti) molar ratio,NaOH concentration,reaction temperature and reaction time on the produced powders were studied.The results indicated that pure PZT powders with homogeneous morphology were obtained in the experimental conditions of Pb/(Zr,Ti) molar ratio 1.7～2.0,NaOH concentration 1 mol/L,200 ℃ and 2 h by the hydrothermal method.更多还原
