Tungsten Production by Electro-Deoxidation |
Supervisor: Dr. İshak KARAKAYA |
|
There has been some effort to
produce tungsten by electrolytic reduction. Among various
electrolytic methods, reduction of tungsten compounds in molten salt
electrolytes seems to be promising. Thermodynamic computations and
experimental studies were performed to shed some light over this
method. Experimental studies will involve the direct electrochemical reduction of tungsten compounds in molten salt mixtures containing CaCl2 as the major component at temperatures
higher than 600oC. Reduced samples will be characterized
by means of X-ray diffraction, scanning electron microscope
and other relevant analysis methods. |

(a)Direct reduction of tungsten oxides; view of electrolysis setup and schematic representation of cell. Electrolysis is conducted between the graphite rod anode
and the tungsten compound cathode at temperatures higher
than 600oC. Early results indicated that metallic
tungsten could be produced by the electrochemical reduction of the tungsten compounds.
(b)X-Ray diffraction spectrum of the one
of the reduced samples, after ten hours
electrolysis and separation processes. It consists of
one phase; tungsten. |
