3. Application

What is Phosphoric Acid China Used For?
Phosphoric acid is mainly used as a fertilizer, which accounts for about 90 percent of production.
nutritional supplements
Food grade phosphoric acid is used to acidify foods and beverages and give them a strong or sour taste.Various phosphates, such as monocalcium phosphate, are used as fillers.Phosphoric acid in soft drinks can cause dental corrosion.Phosphoric acid can also lead to the formation of kidney stones, especially in people who have previously suffered from kidney stones.
Rust removal
Phosphoric acid can be used to remove rust by direct application to rusty iron, steel tools, or other surfaces.Phosphoric acid converts reddish-brown iron(III) oxide and Fe2O3 (rust) into iron phosphate and FePO4.
Liquid phosphoric acid can be used for impregnation, but phosphoric acid used for rust removal is more often prepared in the form of a gel.Various phosphoric acid gel formulations are sold as rust removers.Repeated use of phosphoric acid may be required to convert all the rust.Rust can also be removed with a phosphate conversion coating.This process can leave a black phosphate coating that provides moderate corrosion resistance.
Dental department
Phosphoric acid is used as an etching solution in dentistry and orthodontics to clean and roughen the surface of teeth on which dental appliances or fillings are placed.Phosphoric acid is also found in over-the-counter anti-nausea medications, which also contain high amounts of sugar.This acid is also used in many teeth whitening products to remove plaque that may exist on the teeth before use.
