镧锶镍复合氧化物的制备及热分析

Production of Strontium Substituted Lanthanum Nickel Complex Oxide and Its Thermal Analysis

本文用分析纯的柠檬酸按所需比例与镧锶镍硝酸盐混合生成溶凝胶，产生复合氧化物Ｌａ１－ｘＳｒｘＮｉＯ３（ｘ＝０～１），对复合物的分解机理和热稳定性进行了差热分析与热重分析的测试，得到了一系列曲线并进行了剖析。

The amorphous citrate process has been used to produce La 1 x Sr x NiO 3(x =0～1).The individual solutions for each precursor containing“Anlar”grade citric acid and the metal nitrates in the required proportions were then mixed together to produce the required gels. The decomposition mechanism and the thermal stability of the precursors have been studied using thermogravimetry and differential thermal analysis. A serious of curves have been obtained and analyzed.
