摘　　要：在碳酸稀土生产过程中添加少量消泡剂,即可一次生产出低氯根碳酸稀土,同时缩短反应时间,提高设备利用率。扫描电镜照片可看出加入消泡剂以后晶体排列变得规则有序。During the production of RE carbonates the addition of little erasebubble reagent can not only increase production capacity, but also directly produce product with low chloride ion. The reacting time decreases and the utility ratio of the device increases. The SEM shows that the crystal becomes more ordered after adding the reagent.

关 键 词：稀土 碳酸稀土 消泡剂
