The First is used as pO(2-) indicator electrode and the second as an oxygen pump which allows us to vary the pO(2-) of the ionic melt by electrolysis. Titration of Zr(IV) chlorocomplex by O(2-) ions demonstrated the precipitation of ZrOCl2 and ZrO2. The solubility constants of these compounds were calculated. A Pourbaix type diagram, which summarizes the properties of zirconium species in the melt, was determined \\\\Cserver\\dist\\НБО\\Cтатьи БД ИВТЭ\\Journal of the Electrochemical Society\\JES2004 V.151, N 9. - P.
