氧化镧活性的热分析研究

Study on Active of Lanthana with Thermal Analysis

草酸镧热分解产物氧化镧直接水解得到反应活性高的氢氧化镧，用热重（ＴＧ）和差热分析（ＤＴＡ）研究了氧化镧的活性，方法简单且不易引进其它杂质。

The active of Lanthana was studied by thermogravimetric and differential thermal analysis .The Lanthana was obtained by the thermal decomposition of Lanthanum carbonate and it could produce directly Lanthanum Hydroxide which has high active by hydrolytlic decomposotion reaction. The method is simple and don't bring any other compounds.
