利用TG-FTIR联用仪研究纳米晶La_(0·7)Sr_(0·3)MnO_3的凝胶晶化过程

Study of Nanocrystalline La_(0.7)Sr_(0.3)MnO_3 Gel Crystallization Process by TG-FTIR

采用TG-FTIR联用仪对用溶胶-凝胶(sol-gel)法制备的纳米晶La0.7Sr0.3MnO3(L7S3)的凝胶晶化过程进行了研究,结果表明,复合干凝胶分解生成纳米晶粉是通过逐步分解分阶段形成的。

In this paper we studied the crystallization process of nanocrystalline La0.7Sr0.3MnO3 gel by TG-FTIR. The result showed that the nanocrystalline powder was synthesized from the thermal decomposition progressively of La0.7Sr0.3MnO3 dry gel.
