Various carbon blacks, with widely differing physicochemical properties, were characterized and investigated in corrosion experiments. The oxygen concentration, which was obtained from elemental analysis and infrared analysis, showed a strong correlation to the specific corrosion rate at 1 V in 85% H3PO4 at 170°C. The corrosion rate increased with an increase in the surface concentration of oxygen. A hypothesis to explain this corrosion behaviour is proposed.

Abstract
Various carbon blacks, with widely differing physicochemical properties, were characterized and investigated in corrosion experiments. The oxygen concentration, which was obtained from elemental analysis and infrared analysis, showed a strong correlation to the specific corrosion rate at 1 V in 85% H3PO4 at 170°C. The corrosion rate increased with an increase in the surface concentration of oxygen. A hypothesis to explain this corrosion behaviour is proposed.File in questo prodotto:
