National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Purification of Yttrium by Electrorefining.

PB214763

Publication Date	1973
Personal Author	Fleck, D. C.; Kleespies, E. K.; Kesterke, D. G.
Page Count	20
Abstract	Electrorefining yttrium from selected low-melting yttrium-base alloys was investigated, and various halide systems were studied as potential electrolytes for use in preparing low-oxygen yttrium by electrorefining unalloyed yttrium. Yttrium cathode products having significantly less metallic impurities than the anode materials were prepared from alloys containing nickel, iron, and manganese by electrorefining in LiCl-Ycl3 electrolytes at 900 to 1,000 C. Yttrium-copper and yttrium-magnesium alloys were not suitable as anode feed materials. (Author)
