Used as a pigment in coatings and ceramics due to its stable yellow to brown color and resistance to heat and light.

Employed in lithium-ion battery cathode materials, where it serves as a precursor or component contributing to thermal stability and safety in energy storage devices.

Applied in agriculture as a micronutrient fertilizer providing iron and phosphorus to correct deficiencies in soils, especially in high-pH conditions where iron availability is low. It helps prevent and remedy chlorosis (yellowing) in plants and is popular in organic and low-toxicity farming due to its low toxicity and natural degradability.

Utilized in metal surface treatment to enhance corrosion resistance and promote adhesion in primers and anti-rust coatings.

Additionally, used in laboratory research to study the behavior of iron and phosphate compounds under various conditions.
