What’s ZrN powder?
Zirconium-nitride =105.2, density 7.99g/cm3, and is a light yellow powder. ZrN has high chemical stability and a low decomposition temperature, making it a tough refractory material. This makes ZrN resistant to high temperatures, corrosion and wear. ZrN is an excellent high-temperature structure material, superhard tool and surface protector material. ZrN thin film is a light golden colour with low brightness. It is ideal for areas where titanium dioxide isn’t suitable for coating. ZrN that has been physically vaporized (PVD), is light golden and similar to elemental. ZrN’s room temperature resistivity is 12.0mO*cm. It has a temperature coefficient of resistance of 5.6*10-8O*cm/K. It also has superconducting transitiontemperature of 10.4K. And the relaxation lattice parameter of 0.4575nm. ZrN, single crystal, has a hardness of 22.7+-1.7 GPa. The elastic modulus is 450 GPa.
ZrN carbide’s uses
Zirconium nitride is hard (15 GPa), 10, has a high melting point (32980+-50degC), excellent thermal conductivity (45-50W/mK), low resistance (45-50W/mK), and can withstand corrosion. It is a popular choice for coatings of thermal barriers, mold settings for material process and diffusion barriers.
1. This material is widely used for powder metallurgy and fine ceramic raw material powder. It can also be used to conductive materials and decorative materials. Good conductivity makes it suitable for use as conductive material, such as in the manufacture of electrodes and contacts for molten salt electrolysis. This material can be added to any hard tool.
2. It is used as powder metallurgy or fine ceramic raw material powder.
Zirconium nitride preparation method
A variety of methods are used to synthesize zirconium nutride powder. These include direct nitridation Zr with nitrogen, high energy reactive ball milling, microwave plasma, and aluminum reduction.
1. Direct nitriding (direct nitriding) of metal zirconium, and nitrogen at temperatures of 1100-1200degC
2. Use the zirconium Tetrachloride method. This reaction formula uses zirconium Tetrachloride (ammonia) as the raw material to make zirconium Nitride.
3ZrCl4 + 4NH3-Zr3N4 + 12HCl
2Zr3N4-6ZrN + N2
Zirconium-tetrachloride is first formed an adduct in ammonia. Next, it’s heated to 750°C for zirconium pentaride (Zr3N4). After that, the adduct is further heated to 1200°C for zirconium nutride (ZrN) conversion. Ammonia can react above 1000degC in the presence of sulfuric acids to make zirconium nutride.
