摘要: 在研究固相交换反应过程中,我们对氢氧化镧进行了热重分析,发现氢氧化镧的热分解过程是分两步进行的,由其热重曲线计算了氢氧化镧热分解反应的活化能和反应级数。

Abstract: Thermal decomposition of lanthanum hydroxide proceed in two step, the first step lose two molecules of water and the second step lose one molecule of water, activation energy of these reaction are equal to 16.9 kcal/mol and 43.0 kcal/mol respectively.
