What is Niobium Carbide NbC?

Niobium carbide is a type of metal carbide with the chemical formula NbC.

The look of niobium carbide is brown-gray steel powder with purple luster. It belongs to sodium chloride type cubic crystal system.

The loved one density is 8.47. The lattice constant a=0.447 nm. The melting factor is 3500 ℃. Microhardness > 23.5 Gpa (> 2400 kg/mm2), which is tougher than that of diamond. Elastic modulus 338000N/mm2, thermal development coefficient 6.65 × 10 ^( -6 )/ K, thermal conductivity 14w/(m · K), heat of formation-140.7 kJ/mol, particular heat capability 36.8 J/(mol · K), resistivity 35μΩ · centimeters.

Insoluble in cold and hot hydrochloric acid, sulfuric acid, nitric acid, soluble in warm hydrofluoric acid and nitric acid blended remedy. It is secure at 1000 ℃ and 1100 ℃, and also rapidly oxidized to niobium pentoxide above 1100 ℃. Niobium carbide is easy to melt in titanium carbide, zirconium carbide, tungsten carbide and other compounds to create isomorphous solid solution blend.

Niobium carbide is a very difficult refractory ceramic material. For that reason, it is extremely suitable for machining applications and use security. It is utilized commercially for tool heads for reducing tools. It is normally processed by sintering as well as is a commonly utilized grain growth prevention in cemented carbide. It has high corrosion resistance.

What is Niobium Carbide NbC Used For?

1. With great chemical security and also high-temperature performance, it is a kind of material with high melting point and also high solidity, which is widely utilized in refractory high temperature products and also sealed carbide ingredients.

2. Niobium carbide is a ternary as well as quaternary carbide strong solution element, which is made use of in warm building die, cutting device, jet engine generator blade, shutoff, tail skirt and also rocket nozzle covering with tungsten carbide and molybdenum carbide.

3. As a carbide cemented carbide additive, it is a ternary and quaternary carbide solid remedy component, such as WC-NbC-C ternary system. It can additionally be made use of as a purple synthetic treasure.

4. Used in the production of wear-resistant films and also semiconductor films. It can additionally be made use of as basic material for the manufacturing of molybdenum carbide and for the manufacture of chromium-free special alloys and also engineering ceramics.

What is Element Nb?

Nb (atomic icon: Nb, atomic number: 41) is a D block, fifth household, 5th routine element with an atomic weight of 92.90638. The number of electrons in each shell of Nb'' s Bohr design Nb is 2, 8, 18 and 12, and its electronic setup is [Kr] 4d45s1.

In its important kind, Nb has a gray metal appearance. Among all the aspects, Nb has the largest magnetic infiltration depth and also is just one of the 2nd type of superconductors (in addition to vanadium and technetium) of the three aspects. Nb exists in pyrochlore, its main industrial sources and uranium down payments.
