| | Lithium dihydrogen phosphate Usage And Synthesis |
| Description | Lithium dihydrogen phosphate, also known as LDP, is a White crystalline powder with the formula LiH2PO4. It is soluble in water. LiH2PO4 is usually prepared by a stoichiometric reaction of Li2СO3 and 85% orthophosphoric acid[1]. It is often used as a raw material for the preparation of cathode materials for lithium batteries or as phosphate in chemical reactions. | | Chemical Properties | White crystalline powder | | Uses | Precursor for LiMX2O7 (M = Fe, V; x =P, As) cathode materials.1 | | Uses | Lithium Dihydrogen Phosphate is used in preparation method of lithium hydroxide from lithium-containing low-magnesium brine in lithium phosphate manner. | | General Description | This product has been enhanced for energy efficiency. | | Solubility in water | At 0°C， the solubility of lithium dihydrogen phosphate in water is about 55.8wt % (126.2 g of LiH2PO4 /100 g of water)[1].
At 22°C, the solubility of lithium dihydrogen phosphate corresponds to ~ 153.8 g of LiH2PO4/100 g of water.
At 25°C, it doesn't dissolve in water[2]. | | References | [1] A.P. Voronov, G.N. Babenko, V.M. Puzikov, A.N. Iurchenko, Growth of LiH2PO4 single crystals from phosphate solutions, Journal of Crystal Growth, 2013, 374, 49–52.
