Iron Oxide




Bernalite , Schwertmannite and Green Rusts ).

Some of these oxides are used in Ceramic applications, particularly in Glazing . Many metal oxides provide the colours in glazes after being fired at high temperatures.

Iron oxides yield ) that are widely used in the cosmetic field. They are considered to be nontoxic, moisture resistant, and nonbleeding. Iron oxides graded safe for cosmetic use are produced synthetically in order to avoid the inclusion of ferrous or ferric oxides, and impurities normally found in naturally occurring iron oxides.

IRON OXIDES



  • Iron(III) Oxide (Fe2O3) or ferric oxide is also known as hematite or maghemite in its mineral form, or Rouge as an industrial chemical. Purified, it is used as a Coating in Magnetic audio and computer media. In a dry or alkaline environment it can cause Passivation and inhibits Rust , yet it is also a component of rust.


  • Iron(II,III) Oxide (Fe3O4) or ferrous ferric oxide is also known as magnetite or Lodestone in its mineral form. 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.


It is not difficult to extract iron from ore as compared to the similarly abundant elements Aluminum and Titanium .
