Ce_(0.75)Nd_(0.25)O_(1.875)复合氧化浸出条件的研究

The Study of Leaching Condition of Ce_(0.75)Nd_(0.25)O_(1.875) Complex Oxide

利用Ce3+∶Nd3 +不同配比的二者混合碳酸稀土在不同温度下的焙烧产物为原料 ,研究了不同焙烧温度、不同Ce3+∶Nd3 +配比和不同浸出酸度对Ce0 .75Nd0 .2 5O1.875酸溶性的影响 ,找出生成Ce0 .75Nd0 .2 5O1.

In the experiment, the material was the roasting product of rare earth carbonate mixture with different Ce 3+ ∶Nd 3+ ratio which was roasted in different temperature.The effect of the roasting temperature,Ce 3+ ∶Nd 3+ ratio and the leaching acidity on the leaching of Ce 0.75 Nd 0.25 O 1.875 complex oxide was studied,and the most stable formation condition of the Ce 0.75 Nd 0.25 O 1.875 complex oxide was determined.
