Erbium iodate is an inorganic compound with the chemical formula Er(IO3)3.
Preparation
Erbium iodate can be obtained by reacting erbium periodate and periodic acid in water at 160 °C. The reaction will produce anhydrous and dihydrate crystals.[2]
Properties
Erbium iodate dihydrate is stable below 266 °C, loses two molecules of water at 289 °C, and decomposes at 589 °C to generate iodine and release oxygen.[3]
