Electrochemical Reduction of Tungsten Compounds to Produce Tungsten Powder
Metallurgical and Materials Transactions B, 2010 The production of tungsten by direct current reduction has been investigated. Experimental studies involved the electrochemical reduction of the solid tungsten compounds tungsten trioxide (WO3) and calcium tungstate (CaWO4) in the form of an assembled cathode of porous pellets attached to a current collector.
