Iron(III) phosphate, also ferric phosphate, [4] [5] is the inorganic compound with the formula Fe PO 4. Four polymorphs of anhydrous FePO 4 are known. Additionally two polymorphs of the dihydrate FePO 4 ·(H 2 O) 2 are known.
Iron(II) phosphate, also ferrous phosphate, [3] Fe 3 (PO 4) 2, is an iron salt of phosphoric acid. Natural occurrences. The mineral vivianite is a naturally occurring ...

A phosphate coating is usually obtained by applying to the steel part a dilute solution of phosphoric acid, possibly with soluble iron, zinc, and/or manganese salts. The solution may be applied by sponging, spraying, or immersion. [6] Phosphate conversion coatings can also be used on aluminium, zinc, cadmium, silver and tin. [7] [8]
But since 1948, all phosphate deposits mined in the US have been sedimentary deposits. However, a small amount of phosphate was produced in the 1970s, as a byproduct of iron mining in Missouri. [12] Most phosphate mining is of sedimentary phosphorite, a phosphorus-rich deposit formed under shallow marine conditions. However, a number of US ...
The term phosphate is also used in organic chemistry for the functional groups that result when one or more of the hydrogens are replaced by bonds to other groups. These acids, together with their salts and esters , include some of the best-known compounds of phosphorus, of high importance in biochemistry , mineralogy , agriculture , pharmacy ...
A huge phosphate rock deposit discovered in Norway contains enough minerals to meet the global demand for batteries and solar panels for the next 100 years, according to the mining company that ...
A common example is phosphoric acid, which additionally converts some iron oxide into an inert layer of ferric phosphate. [3] Most of the rust converters contain special additives. [4] They support the rust transformation and improve the wetting of the surface. Applied rust converter
