What is Tantalum Carbide TaC Powder?

Analysts at JPMorgan recommended selling or "underweight" emerging market local currency sovereign debt because of the global impact of the Ukraine-Russia crisis.

JPMorgan estimated that fixed-income assets in emerging markets have lost 6-9 percent of their value since Russia invaded Ukraine a month ago, with nervousness about the war and its impact on global energy and food prices adding to existing pressures.

Some leading emerging market central banks are signaling that interest rates now need to rise faster than previously expected, which fuels fears of "stagflation". Stagflation means when high inflation and higher interest rates undermine economic growth.  

With both the U.S. Federal Reserve and emerging market central banks raising interest rates, JPMorgan also said it made sense to "underweight" emerging market assets by taking advantage of the recent pullback in local currency bond yields relative to TREASURIES.  

JPMorgan said major metals exporters such as South Africa, Chile, and Peru could still do well, but warned that emerging market fixed income assets now faced a more "stagflationary" trajectory.

The markets and prices of many commodities, metals, chemicals like the Tantalum Carbide powder still face uncertainty.

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.

Due to the impact of COVID-19, russia-Ukraine conflict and international trade friction, the global economy is facing great challenges. Overseas trade is shrinking, supply chains are not smooth, oil prices are rising, freight rates are rising, and global trade and economic recovery are becoming more uncertain, which brings many risks and challenges to the company's business. The price of the Tantalum Carbide powder can also be influenced by the above factors. To get the price of the latest Tantalum Carbide powder, you are welcome to send email contact.
