摘要
叙述了以七水硫酸镁和碳酸氢铵为原料,制备碳酸镁和氧化镁的方法,并通过小试对合成碳酸镁的实验温度、时间及反应浓度进行了讨论,找出了正确的工艺条件,并生产出了符合标准的轻质碳酸镁和氧化镁。
The method of the preparation of magnsium carbonate and magnesium oxide from magnsium sulfate and ammonium bicarbonate were described. The reaction time, tempemture and reactant concentration of syhthesis magnesium carbonate have been discussed and correct process condition were found out, light grade of magnesium carbonate and magnesium sulfate were prepared according to stardard.
