Uses of Phosphoric Acid

Phosphoric Acid Uses in Food And Drinks

As one of the most commonly used food additives, food grade phosphoric acid is usually used as sour agent, yeast nutrition, widely used in the production of cola, beer, candy, salad oil, dairy products, beverages, etc... Phosphates are also the important food additive, which can be used as nutrient enhancer.

Phosphoric Acid Uses in Fertilizer

Fertilizer grade phosphoric acid is the most important raw material for the production of phosphate fertilizer, such as superphosphate, potassium dihydrogen phosphate, as well as calcium dihydrogen phosphate feed nutrients. Used as reaction fertilizer in the soil around a granule acidification is generated that improves the utilization of phosphorus applied and available in the rhizosphere. Due to its nitrogen content, it is good for crops that require these nutrients in its initial phase.

Phosphoric Acid Uses in Industrial Fields

  • Used for metal surface phosphating treatment, equipped with electrolytic polishing liquid and chemical polishing liquid for polishing aluminum products.
  • Used in the printing industry to prepare cleaning agents to remove stains on offset printing plates.
  • Used in the production of phosphoric acid refractory cement in the metallurgical industry to increase the life of steel-making furnaces.
  • Used in metal antirust paint in coating industry.
  • Raw materials for production of phosphorus-containing flame retardants. Also used to the production of phosphate ester, raw material for the production of detergents and pesticides.
  • In water treatment. Used as water quality stabilizer and scale inhibitor. Other organic or inorganic phosphates, such as, STPP, SHMP, sodium hypophosphite can be used as dispersant and buffer agent.

Phosphoric Acid Uses in Medicine and Dentistry

  • Phosphoric acid can be used to prepare phosphorus-containing drugs, such as sodium glycerophosphate. It is an important ingredient in over the counter medications to combat nausea.
  • Mixed with zinc powder, phosphoric acid can form zinc phosphate, which is useful in temporary dental cement. In orthodontics, zinc is used as an etching solution to help clean and roughen the surface of teeth.
