The appearance of Niobium Carbide is a brown-gray metallic powder with purple luster. It is part of the sodium chloride type cubic crystalline system.
The relative density is 8.47. The lattice coefficient a=0.447nm. The melting point of corundum is 3500. Microhardness > 23.5Gpa, or more than 2400 kg/mm2, which is much harder than 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.
It is insoluble and insoluble in hot and cool hydrochloric, sulfuric, and nitric acids. It is stable at 1000 to 1100, and quickly oxidized into niobium pentoxide at 1100. To form an isomorphous solid mixture, you can melt it in titanium carbide, zirconium caride, and tungsten carbide.
Niobium carbonide is a highly refractory ceramic that is extremely hard. This makes it ideal for wear protection and machining applications. It is commercially used to make tool heads for cutting instruments. It is often used as a grain growth inhibitor in cemented carbide and is typically processed using sintering. It is highly resistant to corrosion.
What is Niobium-Carbide NbC Used for?
1.It is a material with good chemical stability and high high-temperature performance. It is used extensively in refractory materials high temperature additives and cemented carbide.
2.Niobium carbide is a ternary/quaternary carbide solid component that is used in hotforging die, cutting tools, jet engine turbine blade blade blade, tail skirt and rocketnozzle coating with tungsten and molybdenum.
3. It can be used as a carbide cemented carbonide additive. It can also be used to make a purple artificial gem.
4. This material is used to produce wear-resistant films as well as semiconductor films. It can also serve as a raw material to produce molybdenum caride, as well as for the fabrication of chromium free special alloys and engineering clays.
What is Element NB?
Nb (atomic name: Nb; atomic number 41) is a fifth family, fifth period element and D block having an atomic weight 92.90638. Nb’s Bohr-model Nb contains 2, 8, 18, and 12 electrons, and its electronic configuration [Kr] is 4d45s1.
Nb, as an element, has a gray metallic appearance. Nb, which is an element with the highest magnetic penetration depth of all elements, is also one of the two superconductors. Nb can be found in pyrochlore which is its main commercial source and uranium deposits.
