【摘要】 为生产低氯根荧光级氧化铕研究了草酸沉淀铕过程中温度、加料方式及沉淀产物后处理等对产品中氯根含量的影响，优选出适合生产的工艺条件，应用于生产能有效地控制产品中氯根及其他杂质的含量，得到低氯根的荧光级氧化铕产品。更多还原

【Abstract】 For producing fluorescent-grade low-Cl-Eu2O3, research was made on the ef fects of oxalic acid precipitation conditions (temperature, feeding method etc.) and treat ment methods of the precipitated products on Cl-content in Eu2O3. Optimum technological conditions for production of low-Cl-Eu2O3 have been found.更多还原
