【摘要】 试验采用硼泥作为真空热法炼镁的原料,其中Na₂O的含量为1.26%。为了不使还原出来的大量的碱金属在开罐时遇氧燃烧而点燃镁造成损失,必须采取简单有效的方法使钠和镁分离开来。论文综合了还原罐的容积,产生镁的反应速率和生成镁的量等因素,计算了镁和钠的结晶位置。通过这种方法设计的还原罐能使镁和钠完全分开结晶,得到了良好的效果。更多还原

【Abstract】 In the experiment,boron mud was used to extract magnesium by the method of vacuum thermal. The boron mud contented Na₂O at 1.26%.In order to avoid the magnesic loss resulting from alkali metal burning,when the retort was opened and met oxygen.We must take a simple and effective way to separate sodium from magnesium.Paper combined such factors as the volume of retort,the reaction rate and the mass of produced magnesium,and calculated the crystal location of magnesium and sodium.The retort that was designed in this way can completely separated sodium from magnesium crystal,and obtained good results.更多还原
