N2 - A study is undertaken of the anodic polarization of technical grade, dispersion-hardened Zn-alloyed platinum in borosilicate oxide melts at 1200-1300°C. The mechanism and behaviour of electrode processes are established. A kinetic equation is advanced which considers a slow diffusion of adsorbed oxygen particles on pt surface. The effect of outer polarizing current on mechanical properties of a pt-electrode is estimated. When anodic polarization is small the corrosion of side surfaces of pt specimens is minimal. With an increase in anodic current density above 10 mA/cm2, intercrystalline melting occurs at the interface. This dependence is attributable to higher adhesion of phases due to improved wettability of the metal by glass.
