Global Tantalum Carbide powder market trend 2025-2029 What is Tantalum Carbide TaC Powder? by Newsautbag

The price of nickel and stainless steel rose together. Nickel afternoon hand in hand with stainless steel together turn red up. Due to the temporary easing of geopolitical risks, risk assets are now picking up, nonferrous metals, stock markets, and so on have risen, the overall mood has temporarily improved. Ore prices are strong, the overlay of the epidemic on spot logistics or the formation of a certain impact. Phase, nickel and stainless steel materials to maintain high wide concussion pattern.

Nickel prices based on low inventory, tight supply and demand will still show high wide fluctuations. In addition, the current LME has low liquidity, so its sensitivity to capital will remain relatively high. Shanghai nickel-wide fluctuations are expected to continue in the 200,000-250,000 yuan wide repeated fluctuation trend. While stainless steel is affected by the stronger nickel pig iron, the cost support continues, but note that under the current demand is not effectively released, the upward space may also be affected, the stage is expected to fluctuate between 20000 and 22,000 yuan. The price of nickel produced such fluctuations, indicating that the price of the Tantalum Carbide powder may also be affected to a certain extent.

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.

Southern Copper Corp (SCCO.N) recently said its Peruvian mine remained closed after a six-week standoff with protesters and blamed the Peruvian government for failing to intervene in the safety of its 1,300 workers and their families.  

The company said in a statement that a recent agreement to end protests at the Cuajone mine required the company to withdraw complaints against protest leaders because railways transporting minerals and supplies remained blocked. Production has been suspended since the end of February.  

Peru's Energy Ministry said in a separate statement that it had also reached an agreement with Southern Copper to start talks to find common ground with local communities.  

"If we shut down for a year, the government will stop receiving more than 3.1 billion soles ($830 million) in taxes and royalties, and 8,000 direct and indirect jobs will be lost. This is what we want to avoid, "Southern Copper added in the statement.

Peru has faced a wave of protests from indigenous communities, who accuse mining companies of not providing enough jobs and funding to poor local residents.  

Central bank officials said last week that protests against copper mines such as MMG's Las Bambas and Southern Copper's Cuajone were dragging down the economy.  

Peru is the world's second-largest copper producer and mining is an important source of tax revenue for the country. It is estimated that the supply and prices of the Tantalum Carbide powder will be influenced by that.
