Separating Fe into FeO Fe2O3

Nov 12, 2014You can get a good standard by oxidising a pure iron standard. Mostly FeO then Fe3O4 then a thin layer of Fe2O3. Trouble is, the FeO varies from one side to the other of the wustite phase. If there is Mn in the steel, you get a fascinating pile up rejection in the wustite at the magnetite boundary as it flees the higher oxidation states.

Magnetite: Mineral information, data and localities.

Magnetite is an important iron ore, along with hematite. Nanoinclusions of magnetite crystals cause the iridescence of Rainbow obsidian (Nadin, 2007). Extremely thin layers of 200-nm octahedral crystals of magnetite give some basalt surfaces an iridescent sheen (Nadin, 2007).

6 Magnetic mineralogy

Iron is by far the most abundant transition element in the solar system, so most paleomagnetic studies depend on the magnetic iron bearing minerals: the iron-nickels (which are particularly important for extra-terrestrial magnetic studies), the iron-oxides such as magnetite, maghemite and hematite, the iron-oxyhydroxides such as goethite and ferrihydrite, and the iron-sulfides such as greigite and pyrrhotite.

Magnetite (Ci Shi)

About in the Spring and Autumn Period (770 BC – 476 BC), the phenomenon of magnetite attracting iron was discovered in China. At that time, people likened this type of property to the love of mother to her children, which is also the very source of why magnetite is being called "Ci Shi" in Chinese because "Ci" means a loving mother here.
