Optical properties of magnetite (Fe3O4)

The reflectivity of magnetite (Fe 3 O 4) has been measured in the spectral energy range between 0.03 and 12 eV. The optical constants have been determined by means of a Kramers-Kronig analysis.Hematite Mineral Data,Physical Properties of Hematite : Cleavage: None : Color: Reddish gray, Black, Blackish red. Density: 5.3 : Diaphaneity: Subtranslucent to opaquePhysical Properties of Minerals - Tulane University,Examples of such minerals are magnetite, hematite-ilmenite solid solutions (Fe 2 O 3 - FeTiO 3), and pyrrhotite (Fe 1-x S). Other Properties Other properties that may be diagnostic include chatoyancy, asterism, piezoelectricity, and taste. Familiarize yourself with the meanings of these terms.


the american mineralogist, vol, 55, may-june, 1970 chemical composition and physical prop-erties of magnetite from the ejected plutonic blocks of the,What Are the Uses of Magnetite? | Reference,The magnetite can be reused in this process 90 percent of the time. Magnetite is also used as a source of iron to manufacture iron-based chemicals and fertilizers. Ferric chloride and ferric sulphate are manufactured with magnetite as one of the starting materials. These chemicals are effective in clarifying raw water in water purificationDetermination of nanoparticulate magnetite stoichiometry,,Magnetite can have a range of oxidation states dependent upon the amount of structural Fe2+, which can be discussed quantitatively as the magnetite stoichiometry (x = Fe2+/Fe3+). For magnetite with an ideal Fe2+ content (assuming the Fe 3 O 4 formula), the mineral phase is known as stoichiometric magnetite (x = 0.50).
