氧化钇制备

1.萃取法分解褐钇铌矿所得混合稀土含Y20350％和CeO2约4％，以除铈后的硝酸稀土溶液进料，采用N263-LiNO3体系萃取分组得富钇稀土，经酸溶后再以N263-重溶剂-NH4SCN体系萃取提纯钇，分组后的萃余液为富钇稀土，经直接浓缩、过滤、灼烧，制得氧化钇。其反应方程式如下：

2.金属钇的纳米颗粒根据下列方程式由碱金属的均一还原法制取。得到的副产物在室温下用碳酸洗涤除去。在洗涤过程中，金属钇被氧化成Y2O3，产物使用离心机洗涤分离(15500×G)。

原料：无水YCl3，99.99％纯，不需要进一步纯化。冠醚(15-冠-5，98％)，需要干燥，真空蒸馏进一步纯化。THF(99.94％HPLC级试剂)与KNa合金一起搅拌直到获得稳定的蓝色溶液。反应装置置于充满N2的干燥箱(＜1×10-6H2O,O2)中，溶剂转移使用真空线(133.322×10-6Pa)技术，大气环境下在管式炉中使用铝土燃烧舟进行退火。

3.高于410℃温度下，在热天平［68］中加热分解草酸钇，加热速率为每分钟5.4℃。

4.环烷酸盐酸体系溶剂萃取法　处理独居石，将其富含钇稀土（约含Ｙ２Ｏ３70%）的精矿为原料，配制成0.8mol/L的ＲＥＣｌ３，ｐＨ＝2～3的氯化稀土溶液作为料液，采用环烷酸混合醇煤油溶液自盐酸介质中萃取提纯钇。
