Product Usage-Phosphoric Acid 85%

• The dominant use of phosphoric acid is for fertilizers, consuming approximately 90% of production.
• Food additive：Food-grade phosphoric acid is used to acidify foods and beverages such as various colas and jams.
• It provides a tangy or sour taste. Various salts of phosphoric acid, such as monocalcium phosphate, are used as leavening agents.Phosphoric acid in soft drinks has the potential to cause dental erosion.
• Phosphoric acid also has the potential to contribute to the formation of kidney stones, especially in those who have had kidney stones previously.
• Rust removal：Phosphoric acid may be used to remove rust by direct application to rusted iron, steel tools, or other surfaces.
• The phosphoric acid changes the reddish-brown iron(III) oxide, Fe2O3 (rust), to ferric phosphate, FePO4.
• Liquid phosphoric acid may be used for dipping, but phosphoric acid for rust removal is more often formulated as a gel.
• As a thick gel, it may be applied to sloping, vertical, or even overhead surfaces.
• Different phosphoric acid gel formulations are sold as "rust removers," "rust killers" or "naval jelly." Multiple applications of phosphoric acid may be required to convert all rust.
• Rust may also be removed by phosphate conversion coating.
• This process can leave a black phosphate coating that provides moderate corrosion resistance.
• Medicine：Phosphoric acid is used in dentistry and orthodontics as an etching solution, to clean and roughen the surfaces of teeth where dental appliances or fillings will be placed.
• Phosphoric acid is also an ingredient in over-the-counter anti-nausea medications that also contain high levels of sugar (glucose and fructose).
• This acid is also used in many teeth whiteners to eliminate plaque that may be on the teeth before application.

Other applications

• As a solution for anodizing.
• As an external standard for phosphorus-31 nuclear magnetic resonance (31P NMR).
• As a buffer agent in biology and chemistry. For example, a buffer for high-performance liquid chromatography.
• As a chemical oxidizing agent for activated carbon production, as used in the Wentworth process.
• As the electrolyte in phosphoric acid fuel cells.
• With distilled water (2–3 drops per gallon) as an electrolyte in oxyhydrogen generators.
• As a catalyst in the hydration of alkenes to produce alcohols, predominantly ethanol.
• As an electrolyte in copper electropolishing for burr removal and circuit-board planarization.
• As a flux by metal workers and hobbyists (such as model railroaders) as an aid to soldering.
• In compound semiconductor processing, phosphoric acid is a common wet etching agent: for example, in combination with hydrogen peroxide and water it is used to etch InGaAs selecti.
