Bismuth phosphide is an inorganic compound of bismuth and phosphorus with the chemical formula BiP.^[1]^[2]

Synthesis[]

The reaction of sodium phosphide and bismuth trichloride in toluene (0 °C):^[3]

{\ce {Na3P + BiCl3 -> BiP + 3NaCl}}

When heated in air, bismuth phosphide burns.

When heated in an atmosphere of carbon dioxide, a gradual volatilization of phosphorus is observed.

This compound is oxidized when boiled in water.

All strong acids dissolve it.

The compound is a semiconductor used in high power, high frequency applications and in laser diodes.^[1]
