Russia's insistence on paying for Russian gas in rubles has rattled European countries: Greece held an emergency meeting of suppliers, the Dutch government would urge consumers to use less gas, and the French energy regulator told consumers not to panic. Russian gas meets one-third of Europe's annual energy needs.
Russia said they could expand their demand for ruble payments for other commodities, including oil, grain, fertilizer, coal, and metals, which raised the risk of recession in Europe and the US.
Moscow is expected to unveil its ruble payment plan in early April, but it said it would not immediately ask buyers to pay for gas in rubles.
Western countries have said paying in rubles would be a breach of contract, and renegotiation could take months or longer. This uncertainty has pushed commodity market prices higher.
The supply and prices of other commodities like the niobium carbide powder could also be affected.
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.

The negative electrode material is the carrier of lithium ions and electrons during the charging process of the battery and plays the role of energy storage and release. In the battery cost, the negative electrode material accounts for about 5%-15%, which is one of the important raw materials for lithium-ion batteries. The global sales of lithium battery anode materials are about 100,000 tons, mainly in China and Japan. According to the current growth trend of new energy vehicles, the demand for anode materials will also show a state of continuous growth. At present, the global lithium battery anode materials are still dominated by natural/artificial graphite, and new anode materials such as mesh carbon microspheres (MCMB), lithium titanate, silicon-based anodes, HC/SC, and metal lithium are also growing rapidly.
Our company provides anode materials and niobium carbide powder. If you need to know more anode materials and niobium carbide powder, please feel free to contact us.
