Holmium(III) telluride is an inorganic compound, one of the tellurides of holmium, with the chemical formula Ho2Te3.[1]

Preparation

Holmium(III) telluride can be obtained by reacting tellurium and holmium in a stoichiometric ratio:[2]

2 Ho + 3 Te → Ho2Te3

Properties

Holmium(III) telluride can be dissolved in indium(III) telluride to form a solid solution containing HoInTe3 phase (peritectic temperature 890 K):[3]

Ho2Te3 + In2Te3 → 2 HoInTe3
