Problems solved by technology

[0003] The technical problem to be solved by the present invention: Aiming at the disadvantages of low activity of ferric orthophosphate obtained, low base reserve of raw materials, and poor high-humidity cycle performance, resulting in low low-temperature discharge performance and low rate performance, a water-absorbing glass and oxalyl Acetic acid is mixed, and colloidal orthosilicic acid is obtained after ultrasonic dispersion. Add ferric trichloride and sodium dihydrogen phosphate to this dispersion, and then make ferric chloride and dihydrogen phosphate under the action of organic citric acid and ammonia water titration Sodium is adsorbed and dispersed on the surface of orthosilicic acid, and the hollow microsphere system is obtained by high-temperature calcination and dehydration. By adding lye, it reacts with the internal silica, and then the solid phase is obtained by solid-liquid separation, and the nano-scale is obtained by drying and grinding. The method of highly active hollow microsphere ferric orthophosphate, in order to achieve the purpose of improving its activity and low temperature discharge, rate performance

Description

technical field [0001] The invention relates to a method for preparing ferric orthophosphate of nano-scale highly active hollow microspheres, belonging to the technical field of ferric orthophosphate preparation. Background technique [0002] Iron phosphate is actually iron phosphate, which is another name for iron phosphate. It is a non-toxic white anti-rust pigment, which can replace toxic red lead, lead chrome yellow, zinc chrome yellow, etc. in paint. In addition, it is also a good feed additive and catalyst. Iron phosphate that exists in nature is also called blue iron ore. The iron in iron phosphate is trivalent iron, mostly dihydrate. The initial research was mainly in the fields of agriculture, ceramic glass, steel and surface passivation, etc. Later, it was found that iron phosphate has unique catalytic characteristics, ion exchange capacity and electrochemical performance, and can also be used as a new type of battery cathode material. The material is an excell...
