Russian president demanded that exports of Russian gas to "unfriendly" countries be settled in rubles. The demand has raised concerns in Germany about possible supply disruptions and the impact on industry and households if utilities do not pay in robles. Europe gets about 40% of its gas from Russia. Last year, Europe imported about 155 billion cubic meters. Germany, Europe's largest economy, depends heavily on Russian gas.

The chief executive of Germany's E.ON said the German economy would face "significant damage, which should be avoided if possible" without Russian supplies. He also said it would take Germany three years to wean itself off Russian gas.  

In the event of a supply disruption, Germany's gas network regulator would prioritize home heating over industrial use, so energy-hungry manufacturers such as steelmakers would be the first to suffer, he said.

The volatile international situations will continue to affect the markets and prices of many commodities like 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.

Gas supplies have been in short supply because of the conflict between Russia and Ukraine.  Combined with the situation that other renewable sources cannot produce enough electricity, electricity prices have soared in many parts all over the world. For this reason, I assume the supply and prices of the TaC powder would keep being influenced by the high energy prices.
