Holmium(III) selenide is an inorganic compound with the chemical formula Ho2Se3.
Preparation
[edit]Holmium(III) selenide can be obtained from the reaction of holmium and selenium (in the presence of iodine):[2]
- 2 Ho + 3 Se → Ho2Se3
It can also be prepared by reacting holmium oxide and hydrogen selenide at high temperature.[3]
- Ho2O3 + 3 H2Se → Ho2Se3 + 3 H2O
Properties
[edit]Holmium(III) selenide can form orthorhombic AgHoSe2 in the binary system of silver selenide.[4]
