Electrochemical Study of Sodium Tungstate-Sodium Pyrosulfate Melt and Tungsten Coatings Electrodeposited from Them

The electrochemical behavior of the dimeric complexes of tungsten in tungstate-pyrosulfate melts was studied by potentiometric and voltammetric methods. The six-electron reversible character of the electrode process was established. The effect of the electrolysis parameters on the composition, structure, and properties of deposits was studied.
