Electrochemical Anodic Reaction Rate of Vanadium Metal With Molten Vcl2-vcl3-nacl Mixtures.
NTIS: PB 240 147 :9 pages
The Bureau of Mines has determined the electrochemical rate of anodic dissolution of vanadium metal in a vcl2-vcl3-nacl electrolyte at 860 deg c for the purpose of elucidating the reaction mechanism. Rate measurements were carried out with the help of specially designed equipment capable of continuously recording the weight loss experienced by a cylindrical vanadium anode immersed in the molten salt electrolyte while a constant current is maintained through it. The rate is expressed as a function of current density and vcl3 concentration, and the reaction is interpreted in terms of an adsorption mechanism. Multiple regression analysis of the data gave the following rate equation: rate x 104 (g.Cm-2.Sec-1) = -0.38 + 2.64 Current density (amp.Cm-2) + 0.69 Loge (mole-percent vcl3).
