According to statistics from China Chemical and Physical Power Supply Industry Association， China's export volume and export value of lithium-ion batteries have continued to increase. In 2021, China's exports of lithium-ion batteries were 3.428 billion, with a year-on-year growth of 54.34%. The export of lithium-ion batteries was 28.428 billion DOLLARS, up 78.34% year on year. 

From the battery export destination, so far. China's lithium-ion batteries are mainly exported to the Asia Pacific and the United States and other places. In terms of price, the price of Tantalum Carbide powder, led by lithium-ion batteries, is expected to expand globally. 

Introduction to Tantalum Carbide TaC Powder
Tantalum carbide or TaC is a light brown metallic cubic crystal powder, belonging to the sodium chloride cubic crystal system. The density is 14.3g/cm3.
Insoluble in water, insoluble in inorganic acid, soluble in hydrofluoric acid and nitric acid mixed acid and decomposition. It has strong oxidation resistance and is easily melted and decomposed by potassium pyrosulfate. Has high conductivity, and resistance of 30Ω at room temperature, showing superconductivity.
Tantalum carbide is used for powder metallurgy, cutting tools, fine ceramics, chemical vapor deposition, hard wear-resistant alloy cutting tools, molds, and additives for wear and corrosion resistance structural components to improve the toughness of alloys. The sintered body of tantalum carbide shows a golden color and can be used as watch decoration.

Preparation Methods of Tantalum Carbide TaC Powder
1. In industry, mix tantalum pentoxide powder with solid carbon ball mills, get the mixture reduced and carburized in a non-oxidizing atmosphere (mainly vacuum and argon atmosphere) at 1700℃, to prepare TaC powder with a particle size greater than 2μm.
2. Nano tantalum carbide powder was prepared by heat treatment in the non-oxidizing atmosphere with the liquid precursor method. 5mL of anhydrous ethanol was added into a small beaker containing 0.50gTaCL5, and stirred evenly with a glass rod. Then, it was put into an ultrasonic cleaner with a heating temperature of 55℃ and a working frequency of 40kHz, ultrasonic power was 80W. After ultrasonic oscillation for 5-10min, 0.10g nano-activated carbon was added, and the oscillation continued for 15-20min. Pour it into the crucible and coat it evenly on the inner wall, and dry it with a hot fan. The crucible with the sample was placed in a vacuum hot pressing furnace, and high-temperature treatment was carried out at 1300℃ in a vacuum of 100Pa or hydrogen atmosphere; Or at 1400℃ in argon atmosphere, holding time is 0.5h, the heating rate is 20℃/min. After the experiment, brush the products in the crucible with a brush. 
3. Heat in the air to convert to tantalum pentoxide. Can be fused with potassium pyrosulfate.  By metal tantalum and carbon or tantalum pentoxide and black in an inert atmosphere heated to 1900℃ reaction prepared.
4. Use tantalum pentoxide and methane as the reaction gas, argon as the carrier, using silicon carbide resistance from the external radiation heating, carbonization, or tantalum pentoxide mixed with carbon black, pressurized powder molding, heating in hydrogen or vacuum.
 
Applications of Tantalum Carbide TaC Powder
It is widely used in industry and the military. In cemented carbide, it is widely used as a kind of additive. Its main function is to improve the high-temperature strength of cemented carbide and inhibit the growth of tungsten carbide particles. 
In cutting tools, used as a hard coating to increase the chemical resistance and wear resistance of the base metal; 
In the military, it can be used as a coating for jet engine turbine blades and rocket nozzles, which can significantly improve their ablative resistance and prolong their service life. 
Because of its good conductivity, it can also be used as electrode material, using electric discharge wire cutting into complex shapes; 
And as the second phase particle reinforced metal matrix composites, it can be used in aerospace, metallurgy, building materials, electric power, hydropower, mining, and other fields.

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 powder will continue.
