Ferric Phosphate powder Usage and Synthesis.

As a catalyst, nanoscale iron phosphate can be used as a catalyst is used in dehydrogenation and oxidation, can achieve selective oxidation catalyst, in the field of organic synthesis shows its application potential.

As an additive, iron phosphate can be used as a cement additive and an iron strengthening agent. After adding iron phosphate to magnesium oxide cement, magnesium gum and cement can be obtained, which has good water resistance.

Since iron is trivalent and does not oxidize easily in air, FePO4 can be added to foodstuffs so that the foodstuffs can be stored for a long time, and it can also replenish iron in the human body, improve the ability of hemoglobin to load oxygen, and avoid the occurrence of the symptom of iron-deficiency anemia. As electrode materials and raw materials, trivalent FePOa raw material cost is low, the source is very wide, and has a suitable voltage and high theoretical specific capacity, is a promising cathode material for lithium-ion batteries.

However, FePOa exists in a variety of crystal types, and the electrochemical activity is not the same, if you want to obtain a higher specific capacity, reduce the particle size is an effective means.

FePOa as an electrode material is its main application in industry. It is the delithiation product of LiFePO4, so it can be used as the precursor synthesis raw material of this material. As an antirust pigment, iron phosphate can replace the commonly used toxic red Dan (Pb3O4), zinc phosphate [Zn3(PO4)2], lead chrome yellow (PbCro and zinc chrome yellow main component of ZnCro4〉, and other materials, which are widely used in the antirust pigment of iron and steel products.

The rust prevention mechanism can be considered as follows: iron phosphate dihydrate produces phosphate ions through hydrolysis and the interaction of trivalent iron ions on the surface of iron and steel products to form a FePO4 passivation film, avoiding direct contact between air and moisture and the surface of iron and steel products, thus achieving the purpose of rust prevention.

Uses of Ferric Phosphate powder.

The main use of iron phosphate is in the manufacture of lithium iron phosphate battery materials, catalysts and ceramics. The color of high purity iron phosphate dihydrate is nearly white or light yellowish white, with the loss of crystalline water, the color gradually becomes yellow. When the phosphorus (P) in iron phosphate exceeds the standard, the appearance is grayish white or dark grayish white, and when the iron exceeds the standard, it is dark yellow.

Phosphorus-iron ratio is the most critical indicator to measure the quality of iron phosphate, and is also the most critical factor to determine the quality of lithium iron phosphate. Iron phosphate is mainly used in new energy automobile batteries and 3C industry chain, while a small amount of applications in the ceramics and food fields.

Characteristic of Ferric Phosphate powder.

Iron phosphate FePO4 is also known as iron orthophosphate, high iron phosphate (divalent iron ions as ferrous phosphate), specific gravity of 2.74, the natural existence of FePO4 is also called bluish iron ore, FePO4 iron is trivalent iron in FePO4 to dihydrate mostly, in addition to sulfuric acid, it is difficult to dissolve in other acids, virtually insoluble in water, acetic acid, alcohol.

It is a white, off-white monoclinic crystal powder, for the iron salt solution and sodium phosphate action of the salt, in which the iron is positive trivalent. It is characterized by non-toxicity, low cost and stable structure.

Product method of Bulk Ferric Phosphate powder.

In the presence of oxidizing agents (hydrogen peroxide, sodium chlorate, etc.), the arsenic has been removed from the refined phosphoric acid treatment has been removed from the arsenic and heavy metal ferrous salts (such as ferrous nitrate, ferrous sulfate, etc.), and then add alkali to adjust the value of Ph to 2 ~ 6, that is, the precipitation of iron phosphate.

Ferrous nitrate method first ferrous nitrate solution heated to 95 ~ 110 ℃ to make it all dissolved, in the presence of oxidizing agent, add arsenic and heavy metal removal agent for solution purification, filtration, removal of arsenic and heavy metal impurities, the refined ferrous nitrate solution added to the reactor, under stirring to add the arsenic has been removed from the refined concentrated phosphoric acid and pure ferric phosphate crystal seed, under constant stirring heating reaction 4h, to generate iron phosphate Precipitate, after filtration, washing, drying, the production of edible iron phosphate finished products.

Its 2Fe(NO3)29H2O+2H3PO4+0.5O2[FePO4?2H2O crystal seed]→2FePO42H2O+4HNO3+15H2O ferrous sulfate method firstly, ferrous sulfate is added into distilled water and heated to dissolve all of them, and then in the presence of oxidizing agent, arsenic remover and heavy metal remover are added for purification of the solution, filtered, and the refined ferrous sulfate solution is added into the Reactor, add the refined concentrated phosphoric acid that has removed arsenic under stirring, and then add refined sodium chlorate solution, and react at 85℃ for 30min, and then slowly add edible caustic soda solution, adjust the Ph value to 2~6, so that iron phosphate precipitation precipitation. After filtration, washing, drying, the production of edible iron phosphate finished products.
