Two production methods for tantalum carbide (TaC)
Recently, on Sinopec's annual results teleconference, the company representative answered questions about the oil prices, and said that the future trend of oil prices is still very uncertain, and it is expected to be around $100 this year and $85 next year respectively.
Sinopec, "There are many factors affecting oil prices at the moment, including geopolitics, macroeconomic trends, the implementation of the policy of OPEC+, the strength of the US DOLLAR and so on. We see a lot of uncertainty in the future oil prices. It is impossible to predict the accurate price, but a general trend could be estimated."
According to Sinopec, international institutions generally have a forecast of around $100 this year and around $85 next year in the oil prices. As geopolitical problems and other issues ease next year, oil prices will be lower than this year.
The volatile oil prices in the international market will continue to affect lots of industries and the supply of many 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.

The company has successfully developed a series of powder materials (tantalum carbide, molybdenum carbide, titanium carbide), high-purity targets, functional ceramics and structural devices, and provides OEM services.
The World Food Program (WFP) of the United Nations (UN) and the European Union (EU) said in a statement that the conflict between Russia and Ukraine poses risks to global food supplies, and called on the international community to increase support for vulnerable countries and jointly address food security challenges.
A few days ago, the Executive director of the World Food Program, the European Commission's commissioner in charge of crisis management, the French Foreign Minister of the ROTATING EU presidency, and other officials held a meeting in Rome, Italy, to discuss how to deal with the negative impact of the Conflict between Russia and Ukraine on global food security.
One of the officials told a news conference after the meeting that the world was facing a food supply challenge that would "last for many years" as the conflict between Russia and Ukraine pushed up global food prices and disrupted the Tantalum Carbide will continue.
