摘要
采用NaCl KCl MgCl2 熔盐体系进行了金属镁的电解研究·在电解实验的基础上 ,通过对阴极钢板上沉积的镁的形貌进行SEM观察 ,从而研究了电流强度、电解时间等对镁在阴极上电沉积的影响 ,以及MgO在电解过程中的电泳现象·研究表明 ,增大电流强度 ,单位时间电解槽的产能增大·时间的延长和氟化物的添加 ,都有利于镁在阴极钢板上的沉积 ,而MgO在阴极钢板的沉积 ,则会导致电解条件恶化 ,电流效率大大下降 ,因此应严格控制MgO在电解质中的含量·
The electrolysis of magnesium was carried out with the KCl NaCl MgCl 2 system. Based on electrolysis experiments and SEM analysis, effects of electrolytic current and time on magnesium deposition were studied.Furthermore, the electrophoresis of MgO in the electrolyte was studied. It shows that cell production will be increased by increasing the electrolytic current. The elongation of time and addition of fluoride activator benefit the deposition of magnesium. Deposition of MgO on the steel cathode worsens electrolytic condition and decreases the current efficiency so that it is necessary to control the content of MgO in the electrolyte.
