| 摘 要： | 研究使用2种原料进行PbZr0.52Ti0.48O3的高压合成. 实验结果表明, 以PbO,ZrO2和TiO2(1:0.52∶0.48)为原料, 在1.5 GPa和3.6 GPa压力, 880~1 061 ℃条件下主要形成PbTiO3, ZrO2和Pb三相混合物, 仅在880 ℃附近有少量锆钛酸铅(PZT)相生成. 以Zr0.52Ti0.48O2为B位先驱体, 与PbO混合后进行高压高温合成, 在1.5 GPa, 710~812 ℃条件下形成PbZr0.52Ti0.48O3相, 未发现PbTiO3相. 对高压高温（1.5 GPa, 812 ℃）合成的PbZr0.52Ti0.48O3样品进行变温拉曼测量, 在245 ℃时, 未发生结构相变; 在420 ℃时, 拉曼谱只有177.5,257.7,517 cm-13个峰, 其结构由铁电相转变为立方顺电相, 因此高压合成的PbZr0.52Ti0.48O3居里温度在420 ℃以下.

| Abstract: | The high-pressure synthesis of lead zirconate titanate (PbZr0.52Ti0.48O3 or PZT) ceramics was investigated with two kinds of precursors as raw materials. The XRD and Raman measurements show that with a mixture of PbO and ZrO2 and TiO2(in molar ratio of 1∶0.52∶0.48) as precursor, the three-phase mixture of PbTiO3, ZrO2and Pb can be obtained under 1.5 GPa and 3.6 GPa at 880~1 061 ℃. A few solid solutions of PZT are formed only at 880 ℃. The single phase PbZr0.52Ti0.48O3 can be synthesized from a mixture of PbO and B-state precursor Zr0.52Ti0.48O2 (in molar ratio of 1∶1) in a temperature range of 710~812 ℃ under 1.5 GPa without intermediate phase PbTiO3. The various temperature Raman spectra of the sample synthesized |
