影响氢氧化镁沉降性能的元素

Elements Affecting the Deposition Property of Mg（OH）2

以氨水为沉淀剂与氯化镁反应,直接沉淀法制备氢氧化镁,探讨了加料顺序、反应终点p H值、镁离子浓度、氨水加入速度、陈化过程对氢氧化镁沉降性能的影响。

Magnesium hydroxide was prepared by direct precipitation of magnesium chloride with ammonia water as precipitant.The effect of feeding sequence,p H value of reaction end point,concentration of magnesium ion,adding speed of ammonia water and aging process on the sedimentation properties of magnesium hydroxide were discussed.
