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:[1]
- Dy
2O
3 + 2 (NH
4)(H
2PO
4) → 2 DyPO
4 + 2 NH
3 + 3 H
2O
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 + DyPO
4 → NaDyFPO
4
It reacts with sodium molybdate at high temperature to generate Na2Dy(MoO4)(PO4):[4]
- Na
2MoO
4 + DyPO
4 → Na
2Dy(MoO
4)(PO
4)
