Niobium nitride is a chemical compound of niobium (element 41) and nitrogen (element 7) with the chemical formula NbxNy. At room temperature it is metallic with sputtered films showing a moderate conductivity of 12.2 to 14.3 μΩ cm. It is also very hard having a vickers hardness of around 20 GPa. At low temperatures (~16 K) NbN becomes a superconductor; this property is widely used in precise detectors for infrared light and is being investigated for superconducting resonators.
