The carbides of the Group IV A transition metals titanium, zirconium, and hafnium, and the Group V A transition metals vanadium, niobium, and tantalum are often suggested for load-bearing members for high-temperature applications. Such sugg

hafnium carbide and hafnium diboride films oxidize in quite different ways at elevated temperatures.

Hafnium carbide and hafnium diboride melt at 3950 and 3250°C, respectively.

Hafnium makes the most refractory carbide and nitrides of any know metal. Hafnium nitride has a melting point of 3310°C. Hafnium carbide has a melting point of 3890°C.

Hafnium was first discovered in Copenhagen and was named after the Latin name for the city – Hafinia. Hafnium is a very ductile metal with a brilliant silver lustre.

Zirconium Nitride (ZrN) coating, which is used in a wide range of applications in the industry,offers superior properties. This coating uses a special combination of zirconium and nitrogen and stands out for its excellent surface hardness,

The synthesis of zirconium nitride powders mainly includes direct nitridation of Zr metal with nitrogen, high energy reactive ball milling (RBM), microwave plasma method, benzene-thermal method, aluminum reduction nitridation, magnesium ther

Zirconium nitride nanopowders were prepared by carbothermic nitridation process of powder mixture of zirconium hydroxide gel with carbon black.

The room temperature resistivity of ZrN is 12.0 μΩ·cm, the temperature coefficient of resistivity is 5.6·10-8 Ω·cm/K, the superconducting transition temperature is 10.4 K, and the relaxed lattice parameter is 0.4575 nm. The hardness o

Zirconium nitride is a hard ceramic material similar to titanium nitride and a refractory material similar to cement. Therefore, it is used for refractory materials, cermet, and aboratory crucibles. When the physical vapor deposition coating
