Reaction of zirconium with alkali halide melts
The theoretical model was developed for the description of the reactions of a polyvalent metal with melts containing its compounds, which account for the formation of each species in intermediate oxidation states. This theory was applied to the analysis of literature data on the equilibrium potentia...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | The theoretical model was developed for the description of the reactions of a polyvalent metal with melts containing its compounds, which account for the formation of each species in intermediate oxidation states. This theory was applied to the analysis of literature data on the equilibrium potentials of zirconium electrode in chloride and bromide melts (systems: Zr–KCl; Zr–LiCl-KCl; Zr–KBr; Zr–NaBr-KBr), and also on the vapor pressure of alkali metal upon the fluoride melt (Zr–CsF). The intermediate species were established to form in each chloride and bromide melt. Interaction with evolution of free alkali metal occurs in the fluoride melt, zirconium metal being oxidized to +4 oxidation state. Thermodynamic values for the corresponding reactions were calculated. |
