Ferric phosphate (CAS 10045-86-0), also known as iron phosphate and FePO4, is an inorganic iron salt.

Where is Ferric phosphate used?

• Food manufacturing: fortifies cereals, infant formula and flour with bioavailable iron without altering taste or color
• Nutritional fortification: iron source
• Water treatment: coagulant and flocculant that removes phosphorus from effluents
• Agriculture: active ingredient in approved molluscicide pellets controlling slugs and snails in crop protection
• Pharmaceuticals: iron supplement ingredient in tablets and capsules targeting iron deficiency
• Catalysts.
• Surface treatment of metal surfaces to prevent corrosion and to prepare the surface for painting.
• Raw material for ceramic metal glaze, black glaze and antique glaze.
• Flame retardant in plastics.

Good to know: Food-grade and USP/BP grades serve nutritional and pharmaceutical use; technical-grade material serves agricultural and water treatment applications. Purity levels and particle size specifications vary by grade, so buyers should confirm compliance requirements before sourcing.
