Phosphoric Acid Description
Phosphoric acid, also known as orthophosphoric acid (H3PO4), is a colorless, odorless, and highly soluble inorganic acid. It is an essential chemical compound with a wide range of industrial, commercial, and laboratory applications.
Phosphoric Acid Specification
CAS#: 7664-38-2, M.F.: H3PO4; M.W.: 97.99; Melting Point: 42.35°C,Boiling point: 213°C.
Used as the cleaning and etching agent in TFT-LCD and IC production. Used as the etchant for etching Aluminum and Silicon Nitride film in semi-silicon IC. Produce high-purity phosphates and organic phosphorus products. Absorbs water in wet air and dissoluts in water to produce strong heat and form H3PO4. |
