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.

Electrochemical Reduction of Titanium in Nonaqueous Solvents.

PB96131297

Publication Date	1995
Personal Author	Sibrell, P. L.
Page Count	32
Abstract	Electrorefining of Ti in nonaqueous solvents has been studied by the U.S. Bureau of Mines as a method for recycling impure scrap Ti. Electrochemical behavior of Ti species was investigated using cyclic voltammetry. Research results showed that Ti metal can be dissolved in polar solvents such as dimethylformamide or dimethyl sulfoxide. However, deposition of Ti from these solvents was not successful. Several solvent systems were investigated for electrodeposition of Ti but no deposits were obtained. Reduction of Ti(4+) complexes to Ti(3+) proved to be straightforward, but reduction to lower oxidation states could not be confirmed. Therefore, the prospects for a nonaqueous electrorefining system for Ti metal do not appear promising.
