CYCLIC VOLTAMMETRY AT A METALLIC ELECTRODE - APPLICATION TO THE REDUCTION OF NICKEL, TANTALUM AND NIOBIUM SALTS IN FUSED ELECTROLYTES

Electrodeposition of metals was studied by linear sweep voltammetry at a metallic electrode. A mathematical analysis is available for reacti ons controlled by diffusion. A finite difference algorithm is presente d for digital simulation of complex mechanisms comprising adsorption, multistep reaction and formation of a surface layer of insoluble compo unds. It was used to study the deposition of tantalum and niobium from fused salts.
