In general steel products, phosphorus is a harmful component, but in some special products, the addition of phosphorus can improve certain aspects of steel performance. Phosphate iron is widely used in rolls, cylinder barrels of automobiles, engine rolls, and large castings to improve the corrosion resistance and wear resistance of mechanical parts. Phosphorus partially dissolves in ferrite in steel and partially forms brittle compounds. Phosphoric iron is also used to make shells for grenades and bullets. Due to its fragile performance, a large number of fragments can be obtained after explosion, improving its lethality.
Phosphoric iron is obtained from electric furnaces that manufacture phosphorus. It is a symbiotic compound containing 20-26% phosphorus and 0.1-6% silicon, which can change the corrosion resistance and chip resistance of steel. Phosphate iron can also be used as an alloying agent in the steelmaking industry to produce phosphate. There are two varieties of ferrophosphate produced in China, FeP1 and FeP2, which contain 15% to 20% phosphorus.
It is understood that ferrophosphate cathode materials have many advantages and good prospects in power lithium-ion batteries. Therefore, in order to further improve the performance of this material, avoid repeated design, and achieve patent follow-up, etc. Although China has submitted a large number of patent applications related to lithium iron phosphate, there is a lack of real industrialization, leading to a lack of practical products and technologies for enterprises.
In response to this situation, experts point out that ferrophosphate has relatively strict requirements for the synthesis process due to its own performance, making it difficult to control the stability of the product. Chinese related enterprises should start from the perspective of improving product performance, carry out targeted research and development of key technologies, improve product stability, carry out patent layout, and promote the industrialization of related technologies.
