| 摘 要： | 采用Pb3O4，ZrO2和TiO2等氧化物为原料，Nb2O5为掺杂剂，利用柱面冲击波加载装置合成了Pb(Zr0.95Ti0．05)O3(PZT95／5)粉体。用X射线衍射、红外光谱、扫描电镜和热重-差热分析等多种测试手段对该粉体进行了表征，研究了冲击波技术对合成粉体的结构和性能的影响。结果表明：冲击波能合成钙钛矿型PZT95／5粉体，与固相法合成粉体相比，其晶体结构发生畸变，粉体活性提高。 |

| Abstract: | Pb(Zr_(0.95)Ti_(0.05))O_3 (lead zirconate titanate, PZT95/5) powder was synthesized from the mixture of Pb_3O_4, ZrO_2 and TiO_2 with Nb_2O_5 as dopant using a cylindrical shock-loading device. The effect of the shock-wave technique on crystal structure and properties of the synthesized powders was studied by X-ray diffraction, infrared spectroscopy, scanning electron microscopy and thermogravimetricdifferential scanning calorimetry. The results show that perovskite PZT95/5 powder can be synthesized by shock-wave technique. Compared with powders synthesized by solid-state reaction, distortion is found in the crystal structure of the powders, which can enhance the activity of PZT95/5 powder. |
| Keywords: | lead zirconate titanate powder shock-wave conventional solid-state method synthesis distortion activity |
