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.

Uses

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

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