Abstract
Preparation of high-purity magnesium-yttrium alloys by electroreduction of y2o3 dissolved in a yf3-lif bath and the subsequent deposition of yttrium in a molten magnesium cathode was investigated in laboratory-scale apparatus. Parameters such as temperature, current density, and electrolyte density were studied. Electrolysis was conducted in a specially designed mgo diaphragm cell at temperatures ranging from 780 deg to 970 deg c. Alloys containing up to 55 weight-percent yttrium were prepared at cathode current efficiencies of 21 to 60 percent. Cell design and operation are described, and some of the limiting conditions pertaining to the method are discussed.
