Global niobium carbide powder market trend 2023-2030 Is Niobium Carbide NbC Hard? by Newsnhlhotstove

According to the latest quarterly analysis of the natural gas market released by the International Energy Agency, global natural gas consumption will decline slightly this year and increase slowly in the following years because of soaring prices and the possibility of further reductions in Russian natural gas supplies. Global natural gas use this year is expected to be 0.5% lower than the 2021 level, and global natural gas demand is expected to increase by only 140 billion cubic meters over 2021 by 2025, the report said. The annual growth in 2021 will reach 175 billion cubic meters.

At the same time, the IEA's forecast for natural gas demand growth by 2024 was 60 per cent lower than its previous forecast, mainly due to "a weak economy and a smaller energy shift from coal or oil to natural gas", the report said.

It is worth noting that the South Korean Ministry of Industry, Trade and Resources announced on the same day that it plans to increase the proportion of nuclear power in South Korea's national energy structure to more than 30% by 2030. The proportion is 27.4% in 2021. The department also announced the resumption of the construction of two nuclear reactors. According to reports, after taking office, South Korean President Yoon Sik-Yue rejected the previous government's plan to phase out nuclear power and promised to increase investment in the nuclear power industry, so as to regain South Korea's status as a major exporter of safe nuclear reactors.

In addition, the supply and prices of many international bulk 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.

New Delhi: India's Oil Ministry recently conveyed its intention to five national oil companies including Indian Oil Corp and Bharat Petroleum Resources LTD to assess the possibility of buying shares in Russian oil projects sold by European and American oil majors.  

Bp announced it would give up its 19.75% stake in Rosneft, the Russian oil company.  ExxonMobil said on March 1 that it would exit about $4 billion in assets and terminate all of its Russian operations, including the Sakhalin-1 project in Russia's far East.  

India's oil ministry has asked the overseas investment arm of India's Oil and Gas Corporation to consider buying ExxonMobil's 30 percent stake in the Sakhalin 1 project in Russia's far East. ExxonMobil is the operator of the project and Indian companies already have a 20 percent stake in the project.

Because of the ever-changing international situation, the supply and prices of international bulk niobium carbide powder are still very uncertain.
