| 摘 要： | 用质量分析，Ｘ射线衍射图谱，红外光谱，电镜照片及分析等分析手段，研究了从不同类型风化壳淋积型稀土矿中得到的晶型碳酸稀土与稀土配分的关系，研究结果表明，晶型碳酸稀土的质量普遍优于草酸稀土；晶型碳酸稀土实际上就是简单稀土酸盐的水合结晶体；不同配分的晶型碳酸稀土其结构和晶型较大差异。

| Abstract: | The relation between crystalline RE Carbonates precipitated from various types of leaching liquor of weathered leach-deposited RE ore and its RE composition has been studied by chemical analysis, XRD,IR spectrograph,SEM,TGA and DTA, The results are as follows: The quality of crystalline RE carbonates is better than one of RE oxalates.Crys talline RE carbonates are simple crystallo-hydrates of RE carbonates.The type of crystalline RE carbonates varies with the composition of RE carbonates. |
