镁钇合金质轻耐热,在镁电解槽中加适量的YCl_3,随着钇在液态阴极上的析出,密度逐渐增加而下沉,生产镁钇合金。 关于KCl·NaCl-MgCl_2-YCl_3体系物化性质的研究未见报导。我们对YCl_3,MgCl_2和碱金属氯化物体系的不同组份的密度和表面张力进行了测定。 熔盐电解中,多数是采用氯化钾做为支持电解质,但降低电解温度,有利于减少金属 Magnesium yttrium alloy is light and heat-resistant, and a proper amount of YCl_3 is added to the magnesium electrolyzer. With the deposition of yttrium on the liquid cathode, the density gradually increases and sinks to produce magnesium-yttrium alloy. There is no report on the physicochemical properties of KCl · NaCl-MgCl_2-YCl_3 system. We measured the densities and surface tensions of different components of YCl 3, MgCl 2 and alkali chloride systems. Molten salt electrolysis, the majority of the use of potassium chloride as a supporting electrolyte, but to reduce the electrolysis temperature is conducive to reducing the metal
