Phosphoric acid acido fosforico Chemical formula : H 3 PO 4 Othername : Orthophosphoric acid CAS number : 7664-38-2

Phosphoric acid

Chemical formula : H 3 PO 4 Othername : Orthophosphoric acid

CAS number : 7664-38-2

Appearance : white solid or colourless, viscous liquid (>42 °C)

Applications : Phosphoric acid is a colorless, odorless liquid.

It is a weaker acid than sulfuric acid, nitric acid or hydrochloric acid, and is relatively non-volatile and stable at elevated temperatures.

Phosphoric acid is used in a variety of applications, including etching in the manufacturing of pure semiconductor chemicals and TFT-LCDs, metal surface treatment, phosphates, food additives and beverages, wastewater treatment, refractories, catalysts, and so on.
