Iron Phosphate

	Iron Phosphate Iron phosphate may refer to: * Iron(II) phosphate * Iron(III) phosphate See also * Strengite Strengite is a relatively rare iron phosphate mineral with the formula: FePO4·2H2O. The mineral is named after the German mineralogist (1830–1897). Lavender, pink or purple in hue, it is similar to variscite and is partially soluble, part ..., a hydrated iron phosphate mineral {{Short pages monitor ...

	Iron(II) Phosphate Iron(II) phosphate, also ferrous phosphate, Fe3(PO4)2, is an iron salt of phosphoric acid. Natural occurrences The mineral vivianite is a naturally occurring form of hydrated iron(II) phosphate. Production It can be formed by the reaction of ferrous hydroxide with phosphoric acid Phosphoric acid (orthophosphoric acid, monophosphoric acid or phosphoric(V) acid) is a colorless, odorless phosphorus-containing solid, and inorganic compound with the chemical formula . It is commonly encountered as an 85% aqueous solution, ... to produce hydrated iron(II) phosphate.

	Iron(III) Phosphate Iron(III) phosphate or ferric phosphate is an inorganic compound with the formula Fe PO4. Four polymorphs of anhydrous FePO4 are known. Additionally, two polymorphs of the dihydrate FePO4·(H2O)2 are known. These polymorphs have attracted interest as potential cathode materials in batteries. Structure The most common form of FePO4 adopts the structure of α-quartz. As such the material consists of tetrahedral Fe(III) and phosphate sites. As such the P and Fe have tetrahedral molecular geometry. At high pressures, a phase change occurs to a more dense structure with octahedral Fe centres. Two orthorhombic structures and a monoclinic phase are also known. In the two polymorphs of the dihydrate, the Fe centre is octahedral with two mutually cis water ligands. Uses Iron(III) phosphate can be used in steel and metal manufacturing processes. When bonded to a metal surface, iron phosphate prevents further oxidation of the metal. Its presence is partially responsible for th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
