| 摘要: 以金属的硝酸盐和EDTA为原料,用EDTA-凝胶法制备均匀性好的PLZT超微粉。经FT-IR光谱、热重和差热分析、X射线衍射分析和透射电镜等方法研究表明：硝酸根离子可以加速EDTA-凝胶的热分解,仅在250℃时便有PLZT相生成,除PbO外不出现其他中间相,经600℃煅烧所得到的单一PLZT相超微粉,平均粒径为35nm。 |

| Abstract: Using nitrates and EDTA as raw materials, high homogenous, superfine powders of PLZT have been prepared by the EDTA-gel method. The results of FI-IR spectra, DTA-TG, XRD and TEM show that nitrate ions accelerate the decomposition of the EDTA-gel.The main products are PLZT powders in which there is no other interphases besides PbO phase at 250℃.The superfine powders of monophase PLZT have been produced after calci-nation at 600℃ and the average size is about 35 nm. |
