Iron Phosphate CAS No.10045-86-0

Iron Phosphate CAS No.10045-86-0, also called Orthophosphoric iron, which is an alternative name for iron phosphate. The iron phosphate existing in nature is also called vivianite. The iron in iron phosphate is trivalent iron, mostly in the form of dihydrate.

Dihydrate: FePO₄·2H₂O, Anhydrous: FePO₄. It is mainly used for manufacturing lithium iron phosphate battery materials, and can also be used as a catalyst and for manufacturing ceramics, etc. Orthophosphoric iron can also be used as a nutritional fortifier for iron fortification.

Applications-Iron Phosphate 

Energy Storage and Electronics

  • Lithium Iron Phosphate Batteries: Primary precursor for LiFePO4 cathodes, enabling high-voltage (3.2-3.4V) operation and thermal runaway prevention in EVs and renewables.
  • Catalysts and Ceramics: Additive in oxidation reactions and glazes, enhancing durability and color stability in pottery and electronics.

Food, Feed, and Agriculture

  • Nutritional Supplements: Fortifies cereals, flours, and infant formulas at 0.5-2% as an iron source, boosting hemoglobin levels without metallic aftertaste.
  • Animal Feed: Incorporated at 0.1-0.5% in premixes for poultry and swine to combat iron deficiency and improve growth rates.
  • Molluscicides: Active ingredient in slug and snail baits at 2-5%, targeting pests via ingestion while safe for birds and mammals.

Pharmaceuticals and Cosmetics

  • Iron Therapy: Excipient in tablets and syrups for treating iron-deficiency anemia, with slow dissolution for extended release.
  • Personal Care: Colorant and opacifier in cosmetics, providing natural pigmentation without heavy metal concerns.

Frequently Asked Questions (FAQs)-Iron Phosphate 

What is Iron Phosphate (FePO4)?

Iron Phosphate (FePO4) is a ferric salt with CAS 10045-86-0, used as an iron source in batteries, supplements, and baits. It’s a yellowish, water-insoluble powder delivering stable, bioavailable iron for nutritional and electrochemical needs.

How is FePO4 used in LiFePO4 battery production?

FePO4 is calcined with lithium carbonate at 600-800°C to form olivine-structured cathodes; it provides the iron framework for high safety and longevity, typically at 90-95% loading in precursor mixes.

Is FePO4 safe as a food supplement?

Yes, FePO4 is FDA GRAS and EFSA-approved for iron fortification up to 10 mg/serving, with low bioavailability risks and no pro-oxidant effects in lipid-rich foods like egg products.

What is the shelf life of FePO4?

Stored in sealed, dry conditions below 40°C, FePO4 remains stable for 2-3 years, with no oxidation or moisture uptake due to its inert crystalline structure.

Can FePO4 be combined with other phosphates?

FePO4 integrates well with ammonium phosphates in fertilizers for balanced NPK delivery but may form complexes with excess aluminum—test solubility in blends for agricultural use.

Does FePO4 affect the pH of formulations?

FePO4’s neutral to mildly acidic pH (3.3-6.0) has minimal impact in suspensions, suitable for neutral foods and batteries without requiring additional buffering.

What packaging options are available for FePO4?

We supply 25kg anti-static bags, 50kg fiber drums, and 1000kg palletized totes, all nitrogen-flushed for battery-grade protection and compliant with global transport regulations.
