摘　　要：以卤片和尿素为原料,采用水热合成法制备了高纯度轻质氧化镁,并对工艺条件的影响因素进行分析.结果表明,当卤片与尿素的配比为1∶4.5、反应时间为5 h、反应温度为125℃、洗涤水温度为95℃的条件下制备的氧化镁,转化率高、产品质量好,可达到分析纯轻质氧化镁的标准.Lightweight and high purity magnesium oxide was prepared by hydrothermal method with magnesi- um chloride and urea as raw materials. The process condition and the influence factors were discussed and analyzed in our study. The result shows that most suitable reaction conditions are ： the reaction ratio is 1：4.5, The reaction time is 5 h, the reaction temperature is 125℃ and the temperature is 95℃ of washing water. The products we pre- pared have the merit of high conversion and good quality. The analysis of samples shows that our pure and light- weight products reaches the magnesium oxide standard.
