Neodymium(III) phosphate is an inorganic compound, with the chemical formula of NdPO4.

Properties

Neodymium(III) phosphate hemihydrate can be obtained by the reaction of neodymium(III) chloride and phosphoric acid:[1]

NdCl3 + H3PO4 → NdPO4 + 3 HCl

Its anhydrous form can be obtained by the reaction of silicon pyrophosphate (SiP2O7) and neodymium(III) fluoride.[2]

Properties

Neodymium(III) phosphate reacts with calcium pyrophosphate to obtain Ca9Nd(PO4)7.[3]
