Iron Oxide

There are a number of Iron Oxide s:

Some of these oxides are used in ).

IRON OXIDES

Iron(II) Oxide or ''' Ferrous Oxide ''' (FeO) The black- Colour ed Powder in particular can cause Explosion s as it readily Ignite s.

Iron(III) Oxide or ''' Ferric Oxide ''' (Fe₂O₃) known in its natural state as Hematite (also 'haematite'), but also purified for use as a Coating in Magnetic audio and computer media, where it is known as ferric oxide. Also known as Rouge . This is the form of iron oxide most commonly seen on corroded iron and steel structures ranging from bridges to automobile bodies, and is extraordinarily destructive.

Iron(II,III) Oxide or ''' Ferrous Ferric Oxide ''' (Fe₃O₄), better known as the black-coloured Mineral Magnetite or Lodestone also seen on Mars . Also a main source of iron, magnetite is an iron ore. This form of iron oxide tends to occur when iron corrodes underwater, and so is often found inside tanks or below the waterline of ships.

IRON HYDROXIDES

Iron(II) Hydroxide Fe(OH)₂. green colour.

Iron(III) Oxide-hydroxide FeO(OH) found as the mineral Goethite . Red-brown colour. Also found as the minerals Siderogel , Limonite and Feroxyhyte . There is a variant known as Lepidocrocite .

Iron(III) Hydroxide Fe(OH)₃. Dark brown.

There are also several other variants.
