Holmium phosphide is a binary inorganic compound of holmium and phosphorus with the chemical formula HoP.[1][2][3] The compound forms dark crystals and does not dissolve in water.[citation needed]
Synthesis
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.[citation needed]
HoP belongs to the large class of
NaCl-structured rare earth monopnictides.[4]
Ferromagnetic at low temperatures.[5][6]
HoP actively reacts with nitric acid.[citation needed]
Uses
The compound is a semiconductor used in high power, high frequency applications and in laser diodes.[3]
