Niobium nitride properties and uses

Niobium nitride properties and uses

Light gray with yellowish. The relative density is 8.47I, the melting point is 2300℃; the heat of formation is-237.8kj/mol; the Mohs hardness is 8, the microhardness is 14. 3GPa; the resistivity is 200u. cm. The superconducting transition critical temperature is 15. 6K. Insoluble in hydrochloric acid, nitric acid, sulfuric acid; soluble in concentrated acid solutions of hydrofluoric acid and sulfuric acid, but also soluble in hot alkali or high-concentration lye, and release ammonia. When heated to 500-800°C in the air, niobium pentoxide is produced and nitrogen is released. Niobium nitride decomposes in vacuum to produce metallic niobium. Niobium nitride and titanium carbide, zirconium carbide, vanadium carbide, tantalum carbide, etc. can form solid solutions.

Niobium Nitride Method

Using metal niobium and nitrogen as raw materials, the crushed metal niobium is fed into a nitriding furnace, and nitrogen or ammonia gas is introduced to react at 700-1100°C to directly synthesize niobium nitride. Or add carbon powder to the pulverized metal niobium powder, make it fully mixed, and send it into the reduction furnace, then pass hydrogen and nitrogen into it, and reduce the reaction at a temperature of 1250°C for 2h to obtain niobium chloride.

Overview of Niobium Nitride NbN Powder

Niobium nitride NbN powder is the earliest transition metal nitride, with high melting point, high hardness, good mechanical properties, thermal and chemical stability, good superconductivity, wear-resistant coating, building energy saving, fire-resistant plasma effect and Supercapacitors and other fields. It has been widely used and can also be used to manufacture superconducting quantum devices. In addition, NbN exhibits a surface plasmon resonance (SPR) effect, which indicates that the electromagnetic field near the surface of the material will be enhanced. Therefore, the material can have surface-enhanced Raman scattering (SERS) performance through electromagnetic field enhancement.

Niobium nitride NbN powder application

Niobium nitride NbN powder is an excellent superconducting thin film material, used to manufacture highly stable superconducting quantum instruments.

The main use of niobium nitride is as a superconductor.

Detectors based on it can detect single photons from 1 to 10 microns in the infrared spectrum, which is of great significance to the astronomy and telecommunications industries. It can detect changes in 25 GHz.

NBN superconducting nanowires can be used for strong magnetic field particle detectors

Niobium nitride NbN powder is also used for absorbing anti-reflective coatings.

Niobium nitride-based photocatalysts can absorb 57% of sunlight and can promote the decomposition of water to produce hydrogen, which can be used as fuel for electrochemical fuel cells.
