| 2 | Synthesis of piezoelectric nanocrystalline PZT powder by stearic acid gel method显示文摘PZT nanocrystalline powder was prepared by a stearic acid gel method. The crystallization process from the pre-cursor was monitored by infrared spectroscopy, differential thermal analysis, and thermogravimetric analysis. The nano-sized PZT powder was characterized by X-ray diffraction and transmission electron microscopy. It shows that pure single-phase PZT powder could be obtained at 450°C for 1 h, and the particle size is about 20 nm. With an increase in the calcination temperature, the PZT crystallite size increased. | HAOJunjie WANGXiaohui GUIZhilun LILongtu | 2005 | Rare Metals2005，24，2： | 0 |
