What is Niobium carbide NbC? Niobium carbonideis a form of metal carbide having the chemical composition NbC.
It is a brown-gray powder of metal with purple luster. It’s a sodium chloride-type cubic crystal system.

8.47 is the relative density. The lattice coefficient a=0.447nm. The melting point is 3500. It has a microhardness of > 23.5Gpa (>2400 kg/mm2) which is more difficult than the corundum. Elastic modulus 338000N/mm2, thermal expansion coefficient 6.65×10^(-6)/K, thermal conductivity 14w/(m*K), heat of formation-140.7kJ/mol, specific heat capacity 36.8J/(mol*K), resistivity 35mO*cm.
Hot and cold hydrochloric, sulfuric, and nitric acids are insoluble. It can also be mixed with hot hydrofluoric or nitric-acid solution. It’s stable between 1000-1100. However, it can quickly oxidize to niobium pentoxide over 1100. To form an isomorphous solid solution, you can melt niobium carbide in zirconium carbide, titanium carbide, and tungsten carbide.

Niobium carbonide is a highly refractory, ceramic material. This makes it ideal for wear protection and machining. It’s used in commercial tool heads to cut tools. It can usually be used as a grain growth inhibitor in cemented carbide by using sintering. It’s resistant to high levels of corrosion.

What does Niobium carbide NbC do?
1. It has high chemical stability, high temperature performance and is widely used for refractory materials high in temperatures and cemented carbide additives.

2.Niobium carbide is a ternary or quaternary carbide solution component. This is used in hotforging die, cutting tools, and the jet engine turbine blade blade.

3. This additive is a carbide-cemented carbide component. It can be used as a ternary or quaternary solid solution component in WC-NbC/C ternary systems. This can be used to make a purple artificial gemstone.

4. This material is used to produce wear-resistant and semiconductor films. You can use it as a raw material to produce molybdenum caride or chromium free special alloys. It is also used in the manufacturing of engineering ceramics.

What Is Element Nb
Nb (atomic symbol, Nb; atomic number 41) is an N block, fifth element, fifth family and fifth periodic element, with an atomic count of 92.90638. Nb’s Bohr Model Nb contains 2, 8 and 12 electrons, and has an electronic configuration of [Kr] 4d45s1.
Its elemental form is Nb, which has a grey metallic appearance. Nb, which is composed of vanadium (and technetium), has the greatest magnetic penetration depth of all elements. The main sources of Nb are pyrochlore (its principal commercial source) and the uranium resources.
