What is Ferric phosphate？

Ferric phosphate is an inorganic compound serving as a critical precursor material in the modern industry. Its high purity form is essential for synthesizing lithium iron phosphate (LiFePO₄ or LFP), the cathode material of choice for many lithium-ion batteries due to its safety, stability, and long cycle life. Beyond its pivotal role in energy storage, it is also used as a safe source of iron in food fortification and nutritional supplements, offering excellent stability and minimal reactivity compared to other iron salts.

Application:

1.Lithium-Ion Battery Material:

The primary application. Serves as the essential iron and phosphorus source for the synthesis of high-performance Lithium Iron Phosphate (LiFePO₄) cathode powder, used in electric vehicles (EVs), energy storage systems (ESS), and power tools.

2.Food Fortification:

Ferric phosphate used as a source of dietary iron in food products like flour, cereals, and pasta (often listed as E343(iii) in some regions). It is less likely to cause oxidation or off-flavors compared to ferrous sulfate.

3.Nutritional Supplements:

Ferric phosphate utilized in vitamin and mineral supplements as a gentle, well-tolerated iron source.

4.Industrial Catalyst:

Finds application as a catalyst in certain organic synthesis reactions.

5.Corrosion Inhibitor:

Ferric phosphate used in some metal treatment processes.

Safety profile:

Ferric phosphate is generally considered to have low toxicity. It is not classified as a hazardous substance under GHS. As with any fine powder, inhalation of dust may cause mechanical irritation to the respiratory tract. Eye or skin contact may cause mild irritation. Good industrial hygiene practices, including the use of dust masks and eye protection, are recommended during handling. For food and pharmaceutical grades, it complies with relevant purity and safety standards (FCC, USP, etc.).

Storage requirements:

keep the product dry

relative humidity < 50%

protect product against influences of weather and contamination

Transport & Packaging:

Ferric phosphate for technical applications is solely supplied in packaging of different sizes . It can be packaged in various items: 25 kg bags, 1000 kg bags.
