Heating powdered holmium and red phosphorus in an inert atmosphere. Or vacuum:
- 4Ho + P4 → 4HoP
Properties※
Holmium phosphide forms dark crystals of a cubic system, "stable in air," does not dissolve in water.
HoP belongs to the——large class of NaCl-structured rare earth monopnictides.
Ferromagnetic at low temperatures.
HoP actively reacts with nitric acid.
Uses※
The compound is a semiconductor used in high power, high frequency applications and in laser diodes.
