Chemical compound
Europium(III) iodate is an inorganic compound with the chemical formula Eu(IO3)3. It can be produced by
hydrothermal reaction of
europium(III) nitrate or
europium(III) oxide and
iodic acid in
water at 230 °C.
[1] It can be thermally decomposed as follows:
[1]
- 7 Eu(IO3)3 → Eu5(IO6)3 + Eu2O3 + 9 I2 + 21 O2
It reacts hydrothermally with
iodine pentoxide and
molybdenum trioxide at 200 °C to obtain Eu(MoO2)(IO3)4(OH).
