What is Zirconium nitride?

Chemical properties

Mohs hardness 8+. Slightly soluble in dilute hydrochloric acid and sulfuric acid; soluble in concentrated acids.

Physical properties

Yellow solid. Transition temperature 9 K. Corrosion resistant to steel, basic slag, and cryolithe and molten metals such as Al, Pb, Mg, Zn, Cd, and Bi. Corroded by molten Be, Na, Rb, Ti, V, Cr, Mn, Sn, Ni, Cu, Fe, and Co. Soluble in concentrated HF, slowly soluble in hot H₂SO₄.

The Uses of Zirconium nitride

Zirconium nitride (ZrN) is a hard ceramic material similar to TiN. It is commonly used for coating medical devices, industrial parts (e.g., notably drill bits), automotive and aerospace components and other parts subject to high wear and corrosive environments. ZrN is light gold in color, similar to elemental gold. Hafnium nitride (HfN) is one of the refractory metallic compounds having a melting point of 3310°C.

The Uses of Zirconium nitride

Special crucibles, cermets, refractories.

The Uses of Zirconium nitride

Zirconium nitride is used in cermets, refractories, and laboratory crucibles. It also used for coating medical devices.
