| Hazard Information | Back Directory | [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]
Lithium Dihydrogen Phosphate is used in preparation method of lithium hydroxide from lithium-containing low-magnesium brine in lithium phosphate manner. | [Uses]
