praseodymium oxalate

Aluminum cation in praseodymium-neodymium carbonate can be decreased by the method.

在用碳酸铵沉淀氯化镨钕过程中,某些络合剂可与铝离子形成可溶性络合阴离子,使铝留在溶液中,用此法可降低碳酸镨钕中杂质铝的含量。

The crystallization active zone of praseodymium carbonate was determined by using insitu determination of pH, and the morphology of crystalline praseodymium carbonate was observed by SEM technology.

采用原位pH值测定法确定了碳酸镨的结晶活性区域,并用扫描电镜观测了不同结晶区域结晶碳酸镨的外观形貌。
