Zirconium nitride, ZrN, is a nitride of zirconium.
It is hard and refractory. It has been used recently as an alternative to titanium nitride for coating drill bits. Both coatings are supposed to keep the bit sharper and cooler during cutting. It is also used in refractories, cermets and laboratory cruibles.
