纳米Ce—Zr—O粉末低温固相合成及其表征

采用低温固相法通过对各种影响产物性能的实验条件考察后，优化了纳米Ce—Zr—O粉末的制备工艺，即采用氯化氧锆、碳酸铈、氢氧化钠为原料和水杨酸为络合剂进行研磨，所得的前驱物在室温下干燥和600℃煅烧后，可得到纳米Ce—Zr—O粉末。利用XRD、TG—DTA、拉曼光谱仪等仪器分别对样品的粒度、物相、热稳定性及拉曼特征峰
进行了表征。
The process for Nano—meter Ce —Zr—O Powder preparation was optimized as follc~vs upon investigation of the experimental conditions affecting the product pmp6rties thm~h low temperature solid— phase reaction：grinding with ZrOC12(。)，Ce2(o33)3(。)，NaOV~s)as raw materials and salicylic acid as cm-~plexing agent tO obtain precursor，which is
dried under lX3On'l temperature and calcined at 600℃ tO obtain Nano—meter Ce —Zr—O Powder．The sample powder characterization is tested byⅪ ，TG—UrA，and Raman spec~ ter in respect of its particle size，physical phase，themaal stability and Raman feature．
