Description

Iron(III) Phosphate Dihydrate is a hydrated inorganic salt of iron and phosphoric acid, widely recognized for its role as a high-purity iron and phosphorus source. This compound is valued in industrial and specialty chemical sectors for its consistent quality and predictable reactivity. It is primarily utilized in the production of lithium iron phosphate (LiFePO4) battery cathode materials, as a nutritional fortifier, and in various catalytic and ceramic applications where precise iron content is critical.

Application

• Key precursor material in the synthesis of Lithium Iron Phosphate (LFP) cathode powders for lithium-ion batteries.
• Used as a nutritional iron source in animal feed and food fortification applications.
• Acts as a corrosion inhibitor and surface treatment agent in metal finishing processes.
• Employed in the manufacturing of specialty ceramics, pigments, and glass.
• Serves as a catalyst or catalyst precursor in certain organic synthesis and oxidation reactions.
• Functions as a flame retardant additive in polymers and other materials.
• Used in water treatment for phosphate removal and precipitation processes.
• Applied in laboratory research and analytical chemistry as a standard or reagent.

Quality Control

Our Iron(III) Phosphate Dihydrate is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets precise chemical and physical specifications. We provide Certificates of Analysis (COA) with key parameters such as assay, heavy metal content, and loss on drying. Specifications can be tailored to meet industrial, technical, food (FCC), or battery-grade requirements upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can lead to caking or changes in assay. Keep away from incompatible materials.
