Phosphoric acid
Release time:
Jul 01,2023
Information Summary:
The corrosion change of phosphoric acid to enamel is different from other acids. Generally,
the corrosion resistance of enamel increases with the increase of the concentration of
common acids, but the corrosion resistance of enamel decreases with the increase of the
concentration of phosphoric acid. Because phosphoric acid usually contains fluorine impuri-
ties, long-term corrosion resistance tests over a week are required.
