LITHIUM ORTHOPHOSPHATE Li3PO4

Properties of lithium orthophosphate:

White, melts without decomposition. Poorly soluble in water, the solubility increases in the presence of ammonia hydrate. Decomposes by acids.


Obtaining lithium orthophosphate:

3 LiCl (conc.) + K3PO4 = Li3PO4 ↓ + 3 KCl.

3 LiCl (conc.) + Na2HPO4 + NaOH = Li3PO4 ↓ + H2O + 3 NaCl


Reactions with lithium orthophosphate:

Li3PO4-12 H2O = Li3PO4 + 12H2O (120° C, vacuum).

Li3PO4 + 2 HCl (conc.) = LiH2PO4 + 2LiCl.

Li3PO4 + H2SO4 (diluted) = 2 Li2HPO4 + Li2SO4

Li3PO4 + 3 H2SO4 (conc.) =3 LiHSO4 + H3PO4.

Li3PO4 + 3 CaCl2 (conc.) = 6 LiCl + Ca3(PO4)2 ↓
