Influences of metal ions on the formation of β-FeOOH particles

β-FeOOH particles were synthesized from aqueous FeCl 3 solutions added with different metal ions of Ti(IV), Cr(III), Cu(II) and Ni(II) at varied atomic ratios (metal/Fe) of 0–0.1. Ti(IV) was much more incorporated into the formed particles than Cr(III), Cu(II) and Ni(II). Ti(IV) drastically influenc...

Zusammenfassung:β-FeOOH particles were synthesized from aqueous FeCl 3 solutions added with different metal ions of Ti(IV), Cr(III), Cu(II) and Ni(II) at varied atomic ratios (metal/Fe) of 0–0.1. Ti(IV) was much more incorporated into the formed particles than Cr(III), Cu(II) and Ni(II). Ti(IV) drastically influences the crystallization and particle growth of β-FeOOH, whereas the other metal ions exhibited no marked effect. This result is available for interpretation of the function of Ti in raising resistance to atmospheric corrosion of steels in chloride environments.
