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

Contents

Preparation

Dysprosium(III) phosphate can be obtained by reacting dysprosium(III) oxide and ammonium dihydrogen phosphate at high temperature: [1]

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

Properties

Dysprosium(III) phosphate decomposes into dysprosium oxyphosphate and phosphorus pentoxide above 1200 °C. [2] It reacts with sodium fluoride to obtain NaDyFPO4: [3]

NaF + DyPO4 → NaDyFPO4

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

Na2MoO4 + DyPO4 → Na2Dy(MoO4)(PO4)
