As the world deals with potential supply shortages, oil prices are soaring again, with more dramatic spikes and sudden drops expected.

For consumers, that means more expensive gas for longer - prices at the pump remain above $4 a gallon. For the economy, that means more inflation. In addition to the pressure on consumers, any business that relies on oil -- from airlines and truck drivers to chemical companies and plastics producers -- will face higher costs.

Mr Pickering estimates that 2m to 3m barrels a day of Russian oil shipped by water are frozen out of the market with no direct buyers. Due to the soaring oil price, the price of the TaC powder in the chemical industry will also be greatly affected. He said China and India are continuing to buy Russian crude. "I'm sure there will be others willing to take on more over time," he said. Mr Pickering said he did not expect oil to return to $130 a barrel, but added that it could happen. Francisco Branch, head of commodities and derivatives at Bank of America, said the US market was ready for cyclical price spikes and price swings in the TaC powder.

Introduction to Tantalum Carbide TaC Powder
Tantalum carbide is a kind of transition metal carbide. Black or dark brown metallic powder, cubic crystal system, hard. Melting point 3880℃, boiling point 5500℃, relative density 13.9, hardness 9 ~ 10. Insoluble in water, slightly soluble in sulfuric acid and hydrofluoric acid, soluble in a mixture of hydrofluoric acid and nitric acid.
Its chemical properties are extremely stable. It has excellent physical and chemical properties, such as high hardness, high melting point, good electrical conductivity, and thermal shock resistance, good chemical corrosion resistance, high oxidation resistance, catalytic performance, etc.

Applications of Tantalum Carbide TaC Powder
Tantalum carbide is mainly used for cemented carbide, capacitors, electronic devices, high-temperature components, chemical equipment, and armor piercing shells.

1. Cemented carbide 
Tantalum carbide plays an important role in cemented carbide. It improves the properties of the alloy by improving the fiber structure and phase transformation dynamics, making the alloy have higher strength, phase stability, and processing deformation ability.  Tantalum carbide has a very high melting point (4000℃) and good thermodynamic stability. Tantalum is particularly effective in promoting nucleation and preventing carbon precipitation from nucleated brittle films formed during late solidification. Its main function is to prevent cemented carbide grain from growing up. In addition, it forms a third dispersion phase with TiC besides WC and Co, which significantly increases the thermal shock resistance, crescent hole wear resistance, and oxidation resistance of cemented carbide, and improves its redness and hardness. 
TaC is added into the alloy in different ways, which will greatly affect the properties of the alloy. On the other surface, the TiC-TaC-WC core phase formed by adding TaC to the alloy as TiC-TaC-WC solid solution has a larger sub-crystal size and smaller microscopic strain than the TiC-TaC-WC core phase, and the former one has better physical and mechanical properties and longer cutting life. 
 
2. Electronics industry 
In recent years, transition metal carbides have attracted much attention due to their chemical stability, high hardness, strong oxidation and corrosion resistance, low resistivity, and many other advantages. Carbide nanomaterials show great potential in metal coatings, tools, machine parts, and composites. Among all the carbide nanomaterials, silver carbide is one of the most popular materials, and also one of the materials with the greatest potential. Tantalum carbide not only inherits many advantages of carbide nanomaterials, but also has its own unique side, such as high hardness (Mohs hardness is 9-10 at room temperature, high melting point (about 3880℃), high Young's modulus (283-550 GPa), strong conductivity (conductivity is 32.7-117.4μ ω ·cm at 25℃), high-temperature superconductivity (10.5K), strong resistance to chemical decay and thermal shock, and high catalytic activity for ammonia decomposition and hydrogen separation. 
At present, tantalum carbide powder and whisk tantalum carbide have been prepared by means of carbothermic reduction, thermal plasma, solvothermal, sol-gel, microwave heating, alkali reduction, self-propagating high-temperature synthesis, and high-frequency induction heating sintering.
 
3. Superalloys
Among carbides, the best melting resistance is tantalum carbide (TaC) (melting point 3890℃) and hafnium carbide (HfC) (melting point 3880℃), followed by zirconium carbide (ZrC) (melting point 3500℃). These materials have excellent mechanical properties at high temperatures, far exceeding the best polycrystalline inks. Tantalum carbide, in particular, is the only material that maintains certain mechanical properties over the temperature range of 2900℃ to 3200℃. However, the disadvantage of tantalum carbide is that it is very sensitive to thermal shock, and the low thermal conductivity and high thermal expansion coefficient of carbide become the biggest obstacle to the application of aerospace materials. The addition of tantalum carbide to carbon/carbon composites will have higher thermal conductivity and lower thermal expansion conditions, and exert the oxidation resistance and ablative resistance of refractory metals.

Prior to the impact of COVID-19 on the chemicals and materials industry and the price of the TaC powder, many industry observers expected low to flat growth in 2021 in all regions outside Asia, with many countries seeing slower growth compared to recent years. Operational excellence has long been a hallmark of the TaC powder chemical industry, and many companies are financially able to withstand short-term dips in end-market demand due to rapid leverage from reduced capex on hand.

The analysis shows that, whatever the final course of the pandemic, we can expect the inevitable long-term effects. Workplaces are expected to slowly return to pre-COVID-19 practices. Companies investing in enterprise-wide digital initiatives saw these "payoffs" in the early pandemic environment. For more information about TaC powder, please feel free to contact us.
