Zirkoniumnitride

Zirkoniumnitride, often abbreviated as ZrN, is a ceramic material with the chemical formula ZrN. It is known for its high hardness, excellent thermal conductivity, and chemical inertness. ZrN crystallizes in a cubic structure, similar to sodium chloride. It is a refractory compound, meaning it has a very high melting point, typically above 2900 degrees Celsius. This property makes it suitable for high-temperature applications.

Zirkoniumnitride can be synthesized through various methods, including direct nitridation of zirconium metal at elevated temperatures in a nitrogen atmosphere, or through chemical vapor deposition (CVD) and reactive sputtering techniques. The resulting material can be produced as a powder or as thin films, depending on the desired application.

Industrially, ZrN finds use as a wear-resistant coating for tools and mechanical components due to its hardness and low coefficient of friction. It is also employed in high-temperature crucibles and as a diffusion barrier in microelectronics. Its golden-yellow color has led to its use in decorative coatings and as a pigment. Furthermore, ZrN exhibits good electrical conductivity, which allows for its application in certain electronic devices. Research continues into exploring its potential in areas such as catalysis and thermoelectric materials.
