Chemical compound

Dysprosium(III) phosphate is aninorganic compound with the chemical formula DyPO4.

Preparation

[edit]

Dysprosium(III) phosphate can be obtained by reactingdysprosium(III) oxide andammonium dihydrogen phosphate at high temperature:[1]

Dy2O3 + 2 (NH4)(H2PO4) → 2 DyPO4 + 2 NH3 + 3 H2O

Properties

[edit]

Dysprosium(III) phosphate decomposes intodysprosium oxyphosphate andphosphorus pentoxide above 1200 °C.[2] It reacts withsodium fluoride to obtain NaDyFPO4:[3]

NaF + DyPO4 → NaDyFPO4

It reacts withsodium molybdate at high temperature to generate Na2Dy(MoO4)(PO4):[4]

Na2MoO4 + DyPO4 → Na2Dy(MoO4)(PO4)
