Properties

Phosphoric acid (H3PO4), an important inorganic acid, is an important intermediate product in the production of chemical fertilizer industry. It is used to produce high concentration phosphate fertilizer and compound fertilizer. Phosphoric acid is also the raw material of various phosphates and phosphates used in soap, detergent, metal surface treatment agent, food additive, feed additive and water treatment agent. As the raw material for the production of phosphate fertilizer, it is an aqueous solution of orthophosphoric acid or polyphosphoric acid.
