AluMiniuM phosphate Powder - Preparation Method
Open Data Verified Data
- hydrothermal synthesis method: In a stirred neutralization reactor, sodium aluminate is added to hot water to dissolve into a concentrated solution, heated to 85 °c, and then 85% Phosphoric acid is added for neutralization reaction, A white precipitate was formed, and the final pH was controlled at 4.2 to 4.5. The precipitate and the solution were sent to an autoclave with a stirring device, heated at 250 ° C. For several hours, and then centrifuged. The solid matter is sent to the washing tank, washed with dilute hydrochloric acid solution first, and then washed with clear water for several times to remove water-soluble impurities, and filtered and dried to prepare a finished aluminum phosphate product. The mother liquor of centrifugal separation is sodium dihydrogen phosphate, and the by-product sodium dihydrogen phosphate is recovered and treated.
- double decomposition method: trisodium phosphate and aluminum sulfate are respectively dissolved in water at 85 to 95 ° C. In a dissolution tank, and then filtered with a plate and frame filter press to remove water-insoluble impurities. The two solutions are fed into the reaction vessel for metathesis reaction at the appropriate concentration and molar ratio of UTI, AI2( S04 )3/n,(Na3 P04) -1 1 3], the resulting white colloidal aluminum phosphate was precipitated and then subjected to liquid-solid separation directly with a plate-and-frame filter press. The sodium sulfate is recovered from the separated mother liquor, and the aluminum phosphate left in the filter press is washed with dilute hydrochloric acid solution and then washed several times with clear water to remove impurities such as sulfate. After filtration, drying and grinding, the aluminum phosphate product is obtained.

| production method | hydrothermal synthesis in a stirred neutralization reactor, sodium aluminate is added to hot water to dissolve into a concentrated solution, heating to 85 ℃, then adding 85% Phosphoric acid for neutralization reaction, white precipitate is formed, and the end point is controlled at Ph 4.2~4.5, and then the precipitate and solution are sent to the autoclave with stirring device, centrifugation was performed after heating at 250 °c for several hours. The solid matter is sent to the washing tank, washed with dilute hydrochloric acid solution first, and then washed with clear water for several times to remove water-soluble impurities, and filtered and dried to prepare a finished aluminum phosphate product. The mother liquor of centrifugal separation is sodium dihydrogen phosphate, and the by-product sodium dihydrogen phosphate is recovered and treated. The 2H3PO4 + NaAIO2 → AlPO4 + NaH2PO4 + 2H2O double decomposition method, trisodium phosphate and aluminum sulfate were dissolved in water at 85~95 ° C. In the dissolution tank, and then filtered with a plate and frame filter press to remove water-insoluble impurities. The two solutions were sent to a reaction kettle for metathesis reaction at an appropriate concentration and molar ratio [A12(SO4)3/Na3 PO4 = 1:3] to form a white colloidal aluminum phosphate precipitate, liquid-solid separation was then performed directly with a plate-and-frame filter press. The sodium sulfate is recovered from the separated mother liquor, and the aluminum phosphate left in the filter press is washed with dilute hydrochloric acid solution and then washed several times with clear water to remove impurities such as sulfate. After filtration, drying and grinding, the aluminum phosphate product is obtained. A12(SO4)3+2Na3PO4 → 2AIPO4+3Na2SO4 |
