WebJul 27, 2024 · Table of metal oxides, pH at their IEP (including titanium dioxide, rutile, anatase, and others) In a recent webinar presented by Ana Morfesis titled “ Characterizing the zeta potential & Isoelectric Point of Nanomaterials ” we got such a good turnout that we were not able to address the numerous questions asked during the event. WebFor typical steel/iron/cast iron, when the pH is less than about 4, protective oxide films tend to dissolve and corrosion rates increase. When the pH is between about 4 and 10, soil corrosion is independent of pH. When the pH is greater than 10, the metal becomes passive and corrosion rates decrease with increasing pH. What pH will corrode steel?
