Holmium phosphide is a binary inorganic compound of holmium and phosphorus with the chemical formula HoP.[2][3][4] 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.[1]

HoP belongs to the large class of NaCl-structured rare earth monopnictides.[5]

Ferromagnetic at low temperatures.[6][7]

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.[4]
