It was found that the neodymium oxide content in neodymium carbonate increased with adding temperature increasing and decreased with the feed molar ratio increasing.
A study for preparing neodymium oxide from waste Nd-Fe-B materials was conducted by adopting acid solving-composite salt precipitation process.
利用稀土烧结钕铁硼永磁材料的废料作为原料,选用酸溶-复盐沉淀的化学法,进行了制取氧化钕的实验研究。
The new rare earth pigment was synthesized by adjusting ratio of neodymium and aluminum and adopting different mineralizer, using neodymium oxide and alumina as main raw material.
