Phosphoric acid is mainly used in the manufacture of various phosphate, such as ammonium phosphate, potassium dihydrogen phosphate, disodium hydrogen phosphate, trisodium phosphate, etc and condensation phosphate class.
1, In medical field, phosphoric acid is used in the manufacture of glycerin sodium phosphate, iron phosphate. At the same time, as an etching solution, phosphoric acid is to used to clean and roughen the surfaces of teeth where dental appliances or fillings will be placed. Phosphoric acid is also used in many teeth whiteners to eliminate plaque that may be on the teeth before application. 2, Food-grade phosphoric acid (additive E338) is used to acidify foods and beverages such as various colas because of its sour intensity. 3, In the industrial field, phosphoric acid is an important commodity. It is safer and less potent than muriatic acid, will effectively clean a broad range of surfaces, including concrete and other types of masonry. Otherwise, pure liquid phosphoric acid is used as the electrolyte in phosphoric acid fuel cells. 4, In feed field, phosphoric acid is used to make chemical fertilizer as calcium hydrogen phosphate. 5, In electronics industry, the semiconductor industry use a lot of InP, GaP and phosphide and GaAs InAs or the solid solution, used kH2PO4 and AlPO4 as a piezoelectric crystal, and high purity phosphine as dopant. |
