7.Character :Iron phosphate FePO4, also known as iron orthophosphate or high iron phosphate (divalent iron ion is ferrous phosphate), has a specific gravity of 2.74. The naturally occurring FePO4 is also called blue iron ore, and the iron in FePO4 is trivalent iron, mainly in the form of dihydrates. Except for sulfuric acid, it is insoluble in other acids and almost insoluble in water, acetic acid, and alcohol. It is a white, grayish white monoclinic crystal powder, which is a salt formed by the interaction of iron salt solution and sodium phosphate, in which iron is trivalent. It has the characteristics of being non-toxic, low cost, and structurally stable.Acid-base Character: Iron phosphate exhibits a certain degree of acidity and can undergo neutralization reactions with bases.
Oxidation-Reduction Properties: Iron phosphate has oxidizing properties and can be used in oxidation reactions.
Thermal Stability: The thermal stability of iron phosphate varies with its crystal form. Monoclinic iron phosphate has relatively poorer thermal stability compared to triclinic iron phosphate.
Reactivity: Iron phosphate can be formed from the reaction of ferrous salts with phosphoric acid in the presence of an oxidizing agent.
Usage: Battery Materials Iron phosphate is an important precursor for the production of lithium iron phosphate (LiFePO) cathode materials. Lithium iron phosphate batteries are characterized by high safety, long cycle life, good thermal stability, and relatively low cost, and are widely used in electric vehicles, energy storage devices, solar cells, and other fields.
2. Food Industry:Iron phosphate is used as an iron fortifier in the food industry. It is an ideal iron source additive, commonly used in bread, rice products, and pastes, effectively supplementing the iron content in food.
3. Water Treatment:Iron phosphate can be used for wastewater treatment and heavy metal removal. Its stable chemical properties and strong adsorption capacity make it an ideal material for treating metal pollutants such as iron, aluminum, and manganese in wastewater.
4. Ceramics and Pigments:Iron phosphate is used in the production of ceramics and pigments. As a colorant for ceramic metal glazes, it can provide ceramics with good color and performance.
5. Catalysts:Iron phosphate can be used as a catalyst or catalyst carrier and is widely applied in various catalytic reactions.
6. Rubber and Plastics:In the field of synthetic rubber, iron phosphate can be used as a rubber additive to enhance the antioxidant properties, mechanical processability, and durability of rubber. In addition, iron phosphate is also used in the coatings, inks, and plastics industries.
7. Other Applications:Iron phosphate can also be used to produce flame retardants, feed additives, pharmaceutical intermediates, and moreThe application fields of iron phosphate are continuously expanding. With the development of new energy technologies, its prospects in the battery materials sector are particularly promising.
