Phosphate precipitation is a process in which phosphorus reacts with another substance to form a solid mineral In contrast dissolution of phosphate minerals occurs when the mineral dissolves and releases phosphorus Precipitation and dissolution reactions greatly influence the availability of phosphate in the soilJul 03 32 Mineralization is a process through which organic phosphorus in soil is converted into inorganic phosphorus with the help of soil microb Immobilization on the other hand is the reverse of mineralization During immobilization inorganic phosphorus forms are converted back to organic forms and are absorbed into the living cells of soil

What Is the Main Function of Phosphorus in the Body What is Phosphating Definition from Corrosionpedia

Phosphorus is an essential mineral primarily used for growth and repair of body cells and tissu According to the University of Maryland Medical Center all body cells contain phosphorus with 85 percent found in bones and teeth There together with calcium phosphorus provides structure and Phosphating is the process of converting a steel surface to iron phosphate This is mostly used as a pretreatment method in conjunction with another method of corrosion protection A layer of phosphate coating typically includes iron zinc or manganese crystals Phosphating is also known as phophatizing and phosphate conversion coating
