工业氯化镁

以工业氯化镁和硫氢化钡为原料，采用复分解法合成高纯氢氧化镁。

Using barium hydroxide octahydrate and urea as raw material , barium carbonate is prepared by homogeneous precipitation method .

详细介绍了该工艺的原理及制备过程，在中试的基础上对2万t/a农用硝酸钾和2万t/a工业氯化镁工业装置进行了初步设计与经济效益分析。

The principle and preparation process are introduced in details . The industrial units for agricultural potassium nitrate and magnesium chloride with a capacity of 20 kt / a each are designed and their economic benefits are analyzed .

此条件下产品六水氯化镁纯度可达46%以上，主组分含量达到工业氯化镁标准GB8453-87的要求；氧化镁一步回收率可达74%以上。

The purity of magnesium chloride hexahydrate was over 46 % and the quality of the main component accorded with the requirements of national standard , GB 8453-87 . The recovery of magnesia was over 74 % in this step .
