| titleOfInvention | A kind of iron phosphate, its preparation method and use |
| abstract | The invention provides an iron phosphate, a preparation method and uses thereof. The preparation method of the iron phosphate of the present invention comprises the following steps: mixing an ammonia source and a phosphorus source, adjusting the pH of the solution=1-5 to prepare a bottom liquid; under the protection of an inert gas , mix the iron source and the phosphorus source, add alkali to adjust the pH value of the solution to 1.5-4, and prepare the raw material liquid; at the same time, hydrogen peroxide and the raw material liquid are added dropwise to the bottom liquid, and the molar amount of hydrogen peroxide added is 0.6 of the iron molar amount. ～20 times, the reaction process is continuously stirred, and the reaction is continued for 0.5～3h after the dropwise addition; the solid obtained by separating the reactants is washed with water, dried, and calcined to prepare iron phosphate, and the calcination atmosphere is an oxidative atmosphere, and the calcination temperature is 350 ℃ ～600℃, the calcination time is 2h～14h. The method of the invention is scientific and reasonable, and the prepared iron phosphate has the advantages of low impurity content, stable performance and good batch consistency. |
