Global niobium carbide powder market trend 2022-2027 Is Niobium Carbide NbC Hard? by Newstiohardiman

Risk aversion plunged on the positive news of the Russia-Ukraine talks. After several days of rising oil prices, the price of precious metals continued to fall. Domestic futures markets remain stable for the time being.

Back in international markets, WTI crude futures briefly dipped below $100 a barrel, while Brent crude hit its lowest intraday level in nearly two weeks. Spot gold briefly fell below $1,900 an ounce. Comex gold futures closed down 1.1 percent at $1,918.4 an ounce. Comex silver futures closed down 1.14 percent at $24.91 an ounce. "Recently, crude oil prices have been extremely sensitive to changes in geopolitical news." Traders believe that the current oil price is still in the broad impact, Ukraine will still be a premium in the case, although the market further decline, but should not be too pessimistic, it is recommended to wait and see for the time being. The Ukrainian premium is still there and there will be some volatility in the niobium carbide powder market.

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.

Recently, Rosneft announced that a large oil deposit has been discovered in Bochao Lahai, with reserves equivalent to 82 million tons of oil. The discovery benefited from oil drilling in the Medinskova Landsky area. Rosneft pointed out that the discovery proves the great oil potential of the Timano-Bechula region, which will be the basis for the company to continue to research and develop the region.

In addition, Russian billionaire Vladimir Potanin, the largest shareholder of Norilsk Nickel, said recently that he was prepared to discuss the merger of Norilsk Nickel and aluminum giant Rusal.

"We have received a proposal from Rusal management to discuss a merger with Norilsk Nickel as an alternative to extending the shareholder agreement," Potanin said in an interview with Russia's RBC TV channel. I sent a letter confirming that we agreed to initiate discussions with Rusal on a merger. "

Potanin owns about 35 per cent of Norilsk Nickel. Norilsk Nickel is a major producer of nickel and copper and the world's largest palladium miner. Norilsk Nickel and Rusal had a market capitalization of $49 billion and $15 billion, respectively, as of Monday local time, according to Refinitiv Eikon.
