Changes reddish brown iron oxide (III) and Fe2O3 (rust) into iron phosphate and FePO4.It can be used for impregnation, but phosphoric acid used for rust removal is more often prepared as gel. Different Phosphoric Acid 7664-38-2 gel formulations are sold as rust removers. Multiple uses of it may be required to convert all rust. Rust can also be removed by phosphate conversion coating. This process can leave a black phosphate coating, providing medium corrosion resistance.
