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]
- NdCl
3 + H
3PO
4 → NdPO
4 + 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]
