FORMATION FIELDS AND CURRENT EFFICIENCIES IN THE ANODIC OXIDATION OF ZIRCONIUM: A DIRECT COMPARISON OF HIGH-POTENTIAL FORMATION FIELDS WITH THOSE DERIVED FROM LOW-POTENTIAL CHARGING CURVES
Formation fields at selected constant currents were obtained from high- potential unitary formation rates and polarographic current efficiency measurements carried out over the potential range, 20 to 130 volts. These values are compared with formation fields derived from low-potential unitary formation rates alone, in the potential range below 2 v. Results are reported for abraded Kroll process metal at 750 mu a/cm/sup 2/, for abraded and for chemically polished iodide process metal at 100 and 750 mu a/cm/sup 2/ and 100 mu a/cm/sup 2/, respectively. Ionic current efficiencies are reported for several current densities in the high-potential range and for the low-potential localized oxygen evolution process. (auth)
