The U.S. and its allies plan to impose sanctions on more Russian industries and supply chains.
The US government representatives recently visited Europe to consult with allies on strengthening and enforcing sanctions to punish Russia. They also plan to take action to disrupt their critical supply chains.
The US government claims that the sanctions imposed on Russia since the invasion began on February 24 have proved extremely effective, plunging Russia into a financial crisis. The sanctions include a freeze on the Russian central bank's foreign exchange assets, a ban on hard currency transactions by major Russian banks and wealthy individuals, and export restrictions on advanced semiconductors and other technologies. The sanctions have weakened the Russian economy and left the Kremlin with fewer resources.
The volatile international political situations will continue to affect the markets and prices of many commodities like the Tantalum Carbide.
Overview of Tantalum Carbide(TaC)
Tantalum carbide (TaC) forms a series of binary compounds of tantalum and carbon with the empirical formula TaCx, where x typically varies between 0.4 and 1. They are extremely hard, brittle, refractory ceramic materials with metallic conductivity. They appear as brown-grey powders, usually sintered.
Tantalcarbide is a natural form of tantalum carbide. It is a cubic, extremely rare mineral. The TaC x compound has a cubic (rock salt) crystal structure with x = 0.7–1.0; the lattice parameter increases with x. There are two main crystalline forms of TaC 0.5. The more stable has a cadmium iodide-resistant triangular structure, which transforms to a hexagonal lattice with no long-range order in carbon atoms when heated to about 2000 °C.
An important cermet material, tantalum carbide is used commercially in tool tips for cutting applications and is sometimes added to tungsten carbide alloys. The melting point of tantalum carbide peaks at around 3880°C, depending on purity and measurement conditions; this value is the highest among binary compounds. Only tantalum hafnium carbide may have a slightly higher melting point, around 3942 °C, while hafnium carbide has a melting point comparable to that of TaC.
Production method of tantalum carbide (TaC)
TaC powders of the desired composition are prepared by heating a mixture of tantalum and graphite powders in vacuum or in an inert gas atmosphere (argon). Heating at about 2000 °C using a furnace or arc melting unit. Another technique is the reduction of tantalum pentoxide with carbon at a temperature of 1500–1700 °C in a vacuum or hydrogen atmosphere. This method was used to obtain tantalum carbide in 1876, but it lacked control over the stoichiometry of the product. TaC has been reported to be produced directly from the element by self-propagating high temperature synthesis.
Application of Tantalum Carbide(TaC)
Tantalum carbide(TaC)powder is insoluble in water, almost insoluble in inorganic acid, soluble in mixed acid of hydrofluoric acid and nitric acid, and can be decomposed. Strong anti-oxidation, easily melted and decomposed by potassium pyrosulfate. The resistance is 30Ω at room temperature, showing superconductivity. (TaC) can be used in powder metallurgy, cutting tools, fine ceramics, chemical vapor deposition, hard wear-resistant alloy tools, tools, molds and wear-resistant and corrosion-resistant structural parts to improve the toughness of the alloy. The tantalum carbide (TaC) body is golden yellow and can be used as a decoration for the watch.
It is a heavy brown powder, usually processed by sintering, and is an important cermet material. Sometimes used as a microcrystalline additive for tungsten carbide alloys.
Tantalum carbide(TaC) is an ideal material for aircraft and rockets in the aerospace industry due to its melting point, hardness, elastic modulus, thermal conductivity, shock resistance and chemical stability.
