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.
