Dysprosium(III) phosphate

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

Preparation
Dysprosium(III) phosphate can be obtained by reacting dysprosium(III) oxide and ammonium dihydrogen phosphate at high temperature:


 * Dy2O3 + 2 (NH4)(H2PO4) -> 2 DyPO4 + 2 NH3 + 3 H2O

Properties
Dysprosium(III) phosphate decomposes into dysprosium oxyphosphate and phosphorus pentoxide above 1200 °C. It reacts with sodium fluoride to obtain NaDyFPO4:


 * NaF + DyPO4 -> NaDyFPO4

It reacts with sodium molybdate at high temperature to generate Na2Dy(MoO4)(PO4):


 * Na2MoO4 + DyPO4 -> Na2Dy(MoO4)(PO4)
