Hafnium phosphide (HfP) is a binary inorganic compound of hafnium metal and phosphorus.

Preparation

It can be obtained by heating together hafnium powder and red phosphorus in sealed quartz tube under vacuum at high temperatures.^[4]

The compound is a semiconductor used in high power, high frequency applications and in laser diodes.^[5]

Silica-supported hafinum phosphide (HfP/SiO₂) was used as a solid acid catalyst to drive furfural production from xylan.^[6]^[7]
