摘要
用改进的共沉淀法制备了铁电Ｐｂ（Ｚｒ０．５２Ｔｉ０．４８）Ｏ３（ＰＺＴ）纳米超微粒．通过Ｘ衍射分析、热分析和扫描电镜分析，研究了焙烧温度对ＰＺＴ纳米超微粒性能的影响．实验表明，约在５００℃，沉淀物转变为ＰＺＴ固溶体．随着焙烧温度的升高，ＰＺＴ纳米超微粉晶化度提高，晶粒尺寸增加，其５００，６００，７００℃焙烧温度下的晶粒尺寸分别为１４９，３０１，３７５ｎｍ，晶粒形貌为球形．
Pb(Zr 0.52 Ti 0.48)O 3 (PZT) nanometer ultra micro particles were prepared successfully by improved co precipitation method. The effect of calcining temperature on the properties of PZT nanometer micro particles was investigated by using XRD, DTA TGA, and SEM. The results show that powders co precipitated can be converted to PZT solid solution at the temperature about 500 ℃. The crystallinity of PZT nanometer micro particles and the size of nanocrystal powders of PZT are increased with increasing of the calcining temperature. The particles size of PZT nanocrystal powders obtained at various calcining temperature of 500, 600 and 700 ℃ is 14.9, 30.1 and 37.5 nm. The shape of the particles of PZT nanocrystal powders is spherical.
