Irin olọ́ksíjìn

Awon irin olọ́ksíjìn (Iron oxides) je adapo kemika ti won ni irin ati oksijin. Lapapo, iye awon irin oloksijin ati oxyhydroxides ti a mo je merindinlogun. The uses of these various oxides and hydroxides are tremendously diverse ranging from pigments in ceramic glaze, to use in thermite.

Iron oxide pigment

Àwon oloksijin

• iron(II) oxide, wüstite (FeO)
• iron(II,III) oxide, magnetite (Fe₃O₄)
• iron(III) oxide (Fe₂O₃)
  • alpha phase, hematite (α-Fe₂O₃)
  • beta phase, (β-Fe₂O₃)
  • gamma phase, maghemite (γ-Fe₂O₃)
  • epsilon phase, (ε-Fe₂O₃)

Hydroxides

• iron(II) hydroxide (Fe(OH)₂)
• iron(III) hydroxide (Fe(OH)₃), (bernalite)

Oxide/hydroxides

Àyọkà olórí: iron(III) oxide-hydroxide

• goethite (α-FeOOH),
• akaganéite (β-FeOOH),
• lepidocrocite (γ-FeOOH),
• feroxyhyte (δ-FeOOH),
• ferrihydrite (Fe₅HO₈·4H₂O approx.), or 5Fe₂O₃•9H₂O, better recast as FeOOH•0.4H₂O

• high-pressure FeOOH
• schwertmannite (ideally Fe₈O₈(OH)₆(SO)·nH₂O or Fe³⁺₁₆O₁₆(OH,SO₄)_12-13·10-12H₂O)
