Phosphoric acid

About Phosphoric acid

Specific applications of phosphoric acid include:

• in anti-rust treatment by phosphate conversion coating or passivation
• to prevent iron oxidation by means of the Parkerization process
• as an external standard for phosphorus-31 nuclear magnetic resonance
• in phosphoric acid fuel cells
• in activated carbon production^[33]
• in compound semiconductor processing, to etch Indium gallium arsenide selectively with respect to indium phosphide^[34]
• in microfabrication to etch silicon nitride selectively with respect to silicon dioxide^[35]
• in microfabrication to etch aluminium
• as a pH adjuster in cosmetics and skin-care products^[36]

Properties and Handling

Phosphoric acid is colorless, odorless, and possesses a sour taste with a syrupy viscosity at room temperature. It should be stored in a cool, ventilated area, away from strong bases and metals to ensure longevity and safety. While stable, it is corrosive, so appropriate protective measures must be taken during handling to avoid harm.


Diverse Applications

This compound is widely applied across industries-serving as a key ingredient in fertilizers, food additives, rust removers, dental and orthopedic treatments, and water purification systems. Its adaptability to technical, food, and industrial uses allows it to meet multifaceted market demands for both large-scale industry and laboratory environments.


Quality Assurance and Packaging

Packaged in robust plastic barrels, drums, and IBC tanks, phosphoric acid is preserved for optimal stability and safety in transit and storage. Each batch complies with international standards, ensuring reliable purity and quality whether distributed, exported, or supplied for domestic consumption.
