Phosphoric acid, also known as orthophosphate, is a common inorganic acid that is moderately strong. Its chemical formula is H3PO4 and its molecular weight is 97.995. Not easily volatile, not easy to decompose, and has almost no oxidizing properties. It has acidic properties and is a ternary weak acid. Its acidity is weaker than hydrochloric acid, sulfuric acid, nitric acid, but stronger than acetic acid, boric acid, etc. Phosphoric acid is prone to deliquescence in the air. Heating will dehydrate to obtain pyrophosphate, and further dehydrate to obtain metaphosphate. Phosphoric acid is mainly used in industries such as pharmaceuticals, food, fertilizers, etc., including as a rust inhibitor, food additive, dental and orthopedic surgery, EDIC corrosive agent, electrolyte, soldering flux, dispersant, industrial corrosive agent, raw materials and components for fertilizers, household cleaning products, and also as a chemical reagent.

Mainly used in pharmaceutical,sugar and food industries. In addition to direct consumption in the foodindustry (sour agent, yeast nutrition agent of food industry such as cola,beer, candy, salad oil, dairy products etc.), most of the products are used in the production of food grade phosphates, including sodium phosphates, potassium phosphates, calcium phosphates, zinc phosphates, aluminum phosphates,polyphosphate, compound phosphates etc
LCD Grade : mainly used in LCD screensurface glass treatment and cleaning agent
Agriculture: Phosphoric acid is an important raw material for the production of phosphate fertilizer (superphosphate, potassium dihydrogen phosphate, etc.), but also for the production of feed nutrients (calcium dihydrogen phosphate).
Industry: Phosphoric acid is an important chemical raw material,applied in water treatment industry, electroplating industry, printing industry, dye industry, daily chemical industry, metallurgical industry, etc Its main functions are as follows:
1. Treat the metal surface and generate an insoluble phosphate film on the metal surface to protect the metal from corrosion.
2. Mixed with nitric acid as a chemical polish, to improve the finish of metal surface.
3. Production of detergent, pesticide raw material phosphate ester.
4. Production of raw materials containing phosphorous flame retardant.
Food: Phosphoric acid is one of the food additives, in food as a sour flavor agent, yeast nutrition agent, Coca-Cola contains phosphoric acid. Phosphates are also important food additives that can be used as nutrients an enhancer.
