Abstract
With the aid of acid-base interactions in the melt (by adding F-, it is sho wn that discharge potentials of ionic forms of tungsten may be controlled b y changing shape and composition of electrochemically active species. The p otentials in question are close to those of carbon evolution from carbonic acid. This makes it possible to run their joint reduction and synthesize tu ngsten carbide.
