Chemical compound
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 + H3 PO4 → NdPO4 + 3 HCl
Its anhydrous form can be obtained by the reaction of
silicon pyrophosphate (SiP2 O7 ) and
neodymium(III) fluoride .
[2]
Properties
Neodymium(III) phosphate reacts with
calcium pyrophosphate to obtain Ca9 Nd(PO4 )7 .
