AbstractHigh-purity anhydrous MgCl2-containing molten salt was directly synthesized from MgCl(2)6H(2)O via complex salts dehydration and protection. After that, Mg-Al and Mg-Zn alloys were prepared by electrochemical codeposition. The hydrolysis processes of magnesium chloride hexahydrate in various chloride mixtures were studied. Then, the preparation process was studied and the dehydration mechanism was put forward. NH(4)ClMgCl(2)nH(2)O formed under 300 degrees C inhibits the formation of hydrolysate during the dehydration process. KMgCl3 and K3NaMgCl6 formed above 400 degrees C can further protect the unstable anhydrous MgCl2. Therefore, high-purity anhydrous MgCl2-containing molten salt with w(MgO)/w(MgCl2) being 0.016wt.% was obtained. The current efficiency was above 81% and 97%, respectively, when preparing Mg-Al alloys and Mg-Zn alloys, and the alloying elements were distributed homogeneously in the alloy matrix.
