The model concepts for the mechanisms of formation of electrochemically active species and multielectron processes in ionic nitrate-, carbonate-, boron- and titanium-containing fluoride melts are generalised. The fundamental importance of the acid-base properties of a melt in the mechanism of formation of electrochemically active species is shown for nitrate- and carbonate-containing melts. This fact is confirmed by electrochemical measurements and by calculations of force constants for oxyanions. The optimum form of electrochemically active species has been established; their reduction abilities depend on the cationic composition of a melt, the adsorption properties of the electrode surface and the electric field strength. The bibliography includes 218 references.

Electrochemically active species and multielectron processes in ionic melts

Role of oxide ion concentration on the oxidation behaviour of zirconium in molten NaNO3KNO3 eutectic

Potentiodynamic behaviour of graphite and platinum electrodes in sodium nitrite-potassium nitrite melts

This chapter is devoted to nonmetallic electrode materials, i.e., electrode materials which are neither metallic, nor semiconducting. A large portion of this chapter deals with materials which have proved their worth in actual processes, e.g., carbon and graphite, and another part describes new materials that may prove of much value to the scientist and technologist in the near future.
