Is Niobium Carbide NbC Hard?

Recently, the Russian President hosted a meeting with oil and gas industry representatives.  He said that the refusal of some Western countries to cooperate normally with Russia and deny some Russian energy resources has hit millions of European people deeply and caused an energy crisis. These "unfriendly countries" are experiencing severe inflation, and Russia is also facing the three major challenges of increasing domestic consumption of energy niobium carbide powder are still very uncertain.

What is Niobium Carbide NbC?
Niobium carbide is a kind of metal carbide with the chemical formula NbC.
The appearance of niobium carbide is brown-gray metal powder with purple luster. It belongs to sodium chloride type cubic crystal system.
 
The relative density is 8.47. The lattice constant a=0.447nm. The melting point is 3500 ℃. Microhardness > 23.5Gpa (> 2400 kg/mm2), which is harder than that of 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 35μΩ·cm.
Insoluble in hot and cold hydrochloric acid, sulfuric acid, nitric acid, soluble in hot hydrofluoric acid and nitric acid mixed solution. It is stable at 1000℃ and 1100℃, and rapidly oxidized to niobium pentoxide above 1100℃. Niobium carbide is easy to melt in titanium carbide, zirconium carbide, tungsten carbide and other compounds to form isomorphous solid solution mixture.
 
Niobium carbide is a very hard refractory ceramic material. Therefore, it is very suitable for machining applications and wear protection. It is used commercially for tool heads for cutting tools. It is usually processed by sintering and is a commonly used grain growth inhibitor in cemented carbide. It has high corrosion resistance.
 
What is Niobium Carbide NbC Used For?
1.With good chemical stability and high-temperature performance, it is a kind of material with high melting point and high hardness, which is widely used in refractory high temperature materials and cemented carbide additives.
 
2.Niobium carbide is a ternary and quaternary carbide solid solution component, which is used in hot forging die, cutting tool, jet engine turbine blade, valve, tail skirt and rocket nozzle coating with tungsten carbide and molybdenum carbide.
 
3. As a carbide cemented carbide additive, it is a ternary and quaternary carbide solid solution component, such as WC-NbC-C ternary system. It can also be used as a purple artificial gem.
 
4. Used in the production of wear-resistant films and semiconductor films. It can also be used as raw material for the production of molybdenum carbide and for the manufacture of chromium-free special alloys and engineering ceramics.
 
What is Element Nb?
Nb (atomic symbol: Nb, atomic number: 41) is a D block, fifth family, fifth periodic element with an atomic weight of 92.90638. The number of electrons in each shell of Nb's Bohr model Nb is 2, 8, 18 and 12, and its electronic configuration is [Kr] 4d45s1.
In its elemental form, Nb has a gray metallic appearance. Among all the elements, Nb has the largest magnetic penetration depth and is one of the second kind of superconductors (along with vanadium and technetium) of the three elements. Nb exists in pyrochlore, its main commercial sources and uranium deposits.

Gas prices in European countries are expected to triple if Russian supplies are restricted, according to a press release from Rystad Energy, a Norwegian Energy consultancy.  

The price of natural gas in Europe was $1,200 per 1,000 cubic meters on Tuesday. The benchmark price is already 300 percent higher than a year ago. European gas prices are expected to continue to soar to $3,500 per 1,000 cubic meters if Russian supplies are restricted, according to Analysis by Monitor.

In 2021, Russia delivered 155 billion cubic meters of gas to Europe, accounting for 31 percent of its gas supply, according to an analysis by Monitor Advisors. It would be difficult for Europe to replace Russian gas, which would also destabilize the global LNG market and have a profound impact on Europe's population and economy.

The analysis also said that if Russia stopped supplies now, Europe's current gas reserves would be exhausted by the end of the year, setting in for a cold winter.

In addition, affected by the geopolitical factors, the supply of the niobium carbide powder is erratic and thus its prices are expected to go higher in the future.
