Lanthanum orthophosphate, LaPO4

Lanthanum orthophosphate, LaPO4, is obtained as a white, amorphous precipitate by adding phosphoric acid or sodium orthophosphate to a solution of a lanthanum salt (Cleve). It may be obtained in the crystalline form by heating lanthana with molten potassium metaphosphate. The double salt 2LaPO4.K3PO4 may be prepared by saturating molten potassium pyro- or ortho-phosphate with lanthana.
