碳酸稀土焙烧过程中Ce_(0.75)Nd_(0.25)O_(1.875)生成条件的研究

The Study of Formation Condition of Ce_(0.75)Nd_(0.25)O_(1.875) Complex Oxide during Rare Earth Carbonate Roasting Process

利用纯Ce2 与Nd2 O3 为原料制得的不同Ce3 + ∶Nd3+ 配比的混合碳酸稀土 ,研究了不同焙烧温度和Ce3 + ∶Nd3+ 配比条件对Ce0 .75Nd0 .2 5O1.875的影响 ,用X射线衍射仪分析了焙烧产物 ,得出了Ce0 .75Nd0 .2 5O1.

In the experiment,the rare earth carbonate was made from pure CeO 2 and Nd 2O 3 with different Ce 3+ ∶Nd 3+ ratio.The effects of the rasting temperature and Ce 3+ ∶Nd 3+ ratio on the formation of the Ce 0.75 Nd 0.25 O 1.875 complex oxide were studied. The roasting products were analyzed by XRD. The optimal formation condition of Ce 0.75 Nd 0.25 O 1.875 complex oxide was determined.
