PS0108 Phosphoric Acid (CAS No. 7664-38-2)

Catalogue Number	PS0108
Purity	H3PO4
CAS Number	7664-38-2

Industries use phosphoric acid to remove rust from metal surfaces. Food manufacturers add phosphoric acid as an additive to acidify foods and beverages such as Cola. Recent studies at Stanford Advanced Materials report a 90% rust removal efficiency under controlled laboratory conditions. Engineers use phosphoric acid to maintain product integrity in food processing. It has been utilised in both medicine and dentistry for diagnostic and therapeutic procedures.

Phosphoric Acid Specification CAS#: 7664-38-2, M.F.: H3PO4; M.W.: 97.99; Melting point: 42.35°C, Boiling point: 213°C. It is used as a cleaning and etching agent in TFT-LCD and IC production. It is utilised as an etchant for aluminium and silicon nitride films in semiconductor ICs. It is employed to produce high-purity phosphates and organic phosphorus products. It absorbs water from humid air and dissolves in water, thereby releasing substantial heat and forming H3PO4.
