納米Ce—Zr—O粉末低溫固相合成及其表征

采用低溫固相法通過對各種影響產(chǎn)物性能的實驗條件考察后，優(yōu)化了納米Ce—Zr—O粉末的制備工藝，即采用氯化氧鋯、碳酸鈰、氫氧化鈉為原料和水楊酸為絡合劑進行研磨，所得的前驅(qū)物在室溫下干燥和600℃煅燒后，可得到納米Ce—Zr—O粉末。利用XRD、TG—DTA、拉曼光譜儀等儀器分別對樣品的粒度、物相、熱穩(wěn)定性及拉曼特征峰
進行了表征。
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．
