5, Applications: Yellow phosphorus (YP) Concentrated phosphoric acids, which can consist of 70% to 75% P2O5are very important to agriculture and farm production in the form offertilisers. Global demand for fertilizers LED to large increases inphosphate production in the second half of the 20th century. Other uses;

* Phosphates are utilized in the making of special glasses that are used for sodium lamps.
* Bone-ash, calcium phosphate, is used in the production of fine China.
* Sodium tripolyphosphate made from phosphoric acid is used inlaundry detergents in several countries, and banned for this use inothers.

* Phosphoric acid made from elemental phosphorus is used infood applications such as soda beverages. The acid is also a startingpoint to make food grade phosphates. These include mono-calciumphosphate which is employed in baking powder and sodiumtripolyphosphate and other sodium phosphates. Among other uses theseare used to improve the characteristics of processed meat and cheese. Others are used in toothpaste. Trisodium phosphate is used in cleaningagents to soften water and for preventing pipe/boiler tube corrosion.

* Phosphorus is widely used to make organophosphoruscompounds, through the intermediates phosphorus chlorides and the twophosphorus sulfides: Phosphorus pentasulfide, and phosphorussesquisulfide. Organophosphorus compounds have many applications, including in plasticizers, flame retardants, pesticides, extractionagents, and water treatment.
* Phosphorus is also an important component in steelproduction, in the making of phosphor bronze, and in many other relatedproducts.

* White phosphorus is used in military applications asincendiary bombs, for smoke-screening as smoke pots and smoke bombs, and in tracer ammunition.
* Red phosphorus is essential for manufacturing matchbookstrikers, flares, safety matches, pharmaceutical grade and streetmethamphetamine, and is used in cap gun caps.
* Phosphorus sesquisulfide is used in heads of strike-anywhere matches.
* In trace amounts, phosphorus is used as a dopant for N-type semiconductors.
* 32P and 33P are used as radioactive tracers in biochemical laboratories.
