High Purity Tantalum Carbide TaC Powder Cas 12070-06-3, 99.9%

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 Tantalum Carbide 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 Tantalum Carbide powder.

About Tantalum Carbide TaC Powder:
Tantalum carbide is a metallic cubic crystalline powder that forms a binary chemical compound family of tantalum and carbon. They are extremely hard, fragile refractory ceramic materials with metallic conductivity. They appear as brownish-gray powders and are usually processed by sintering. It belongs to the sodium chloride type cubic crystal system. At present, tantalum carbide is also used as a cemented carbide sintered grain growth inhibitor, which has a significant effect on inhibiting grain growth, with a density of 14.3g/cm3.
 
Tantalum carbide is insoluble in water, hardly soluble in inorganic acid, soluble in a mixed acid of hydrofluoric acid and nitric acid, and can be decomposed. Strong oxidation resistance, easily melted and decomposed by potassium pyrosulfate. Tantalum carbide has high electrical conductivity, with a resistance of 30Ω at room temperature, showing superconducting properties. Tantalum carbide can be used in powder metallurgy, cutting tools, fine ceramics, chemical vapor deposition, hard wear-resistant alloy tools, tools, molds, and wear-resistant and corrosion-resistant structural components to improve the toughness of the alloy. The sintered body of tantalum carbide is golden yellow and can be used as a watch decoration.
 
The bond between tantalum carbide and carbon atoms is a complex mixture of ions, metals and covalent contributions, and these carbides have very hard and brittle materials due to strong covalent components. For example, TAC has a microhardness of 1600-2000 kg/mm2 (~9μH) and an elastic modulus of 285gPa, and the corresponding values of tantalum are 110kg/mm2 and 186gPa. The carbon content in TAC increases hardness, yield stress and shear stress.
 
As an important cermet material, tantalum carbide is sometimes added to the tungsten carbide alloy when it is commercially used for cutting applications. Depending on the purity and measurement conditions, the melting point of tantalum carbide reaches its peak at about 3880°C. This value is the highest value among binary compounds. Only tantalum carbide ha can have a slightly higher melting point of about 3942°C, while the melting point of carbide clam is comparable to TaC. Feel free to send an inquiry to get the latest price if you would like to buy Tantalum Carbide TaC Powder in bulk.

Properties and Applications of Tantalum carbide TaC powder:
Tantalum carbide (TaC) is an extremely hard (Mohs hardness 9-10) refractory ceramic material, commercially used in tool bits for cutting tools. The hardness is exceeded by diamond.  
It is a heavy, brown powder usually processed by sintering, and an important cermet material. 
It is sometimes used as a fine-crystalline additive to tungsten carbide alloys. 
Tantalum carbide has the distinction of being the stoichiometric binary compound with the highest known melting point, at 4150 K (3880&deg;C) and boiling point, at 5500 oC. 
The substoichiometric compound TaC0.89 has a higher melting point, near 4270 K (4000&deg;C).

How is Tantalum Carbide TaC Powder produced?
The Tac powder of the desired composition is prepared by adding a mixture of heating and graphite powder in a vacuum or an inert gas atmosphere (argon). The heating was performed at a temperature of about 2000 &deg; C using a furnace or arc melting. The alternative technology is reduced by carbon tantalum oxide in a vacuum or hydrogen atmosphere at a temperature of 1500-1700 &deg; C. This method is used for carbonized tantalum in 1876, but it lacks thermometrically controlled control of the product. Direct production TAC is produced directly from the component by self-propagating high-temperature synthesis.
 
Application of Tantalum Carbide TaC Powder:
The main use of tantalum carbide is carbide, capacitors, electronic devices, high-temperature components, chemical equipment and ferrite. Carbides are typically added to tungsten carbide/cobalt (WC / CO) powder wear to enhance the physical properties of the sintering structure.
The tantalum carbide also serves as a grain growth inhibitor to prevent large particles from forming a material to produce an optimum hardness.
It is also used as steel mold coatings in aluminum alloy injection molding. While providing hard, wear-resistant surfaces, it also provides low friction mold surfaces.
Carbides are also used to produce sharp instruments with extreme mechanical resistance and hardness. In addition, tantalum carbide can also be used in the following:
1.Cemented carbide
The tantalum carbide plays an important role in the cemented carbide, which improves alloy properties by improving fibrous tissue and phase transformation kinetics, making alloys with higher strength, phase stability, and processing deformation capabilities.
2. Electronic industry
Natunction not only inherits many advantages of carbide nanomaterials but also has its own unique side. Such as high hardness (normal temperature is 9-10, high melting point (approximately 3880 &deg; C), Yang's modulus (283-550 GPa), strong conductivity (32.7-117.4 &mu;&Omega; &middot; CM at 25 &deg; C in electrical conductivity) ), High-temperature superconducting (10.5k), anti-chemical corrosion candles and heat shock ability, highly catalytic activity of ammonia decomposition and hydrogen separation.
3. High-temperature alloy
In carbide, the melting is preferably a tantalum carbide(TAC) (melting point 3890 &deg; C) and carbide (HFC) (melting point 3880 &deg; C), followed by carbide (ZrC) (melting point 3500 &deg; C). At high temperatures, these materials have excellent mechanical properties, greatly exceeded the best polycrystalline graphite, especially carbonized, is the only material that maintains certain mechanical properties in the temperature range of 2900 &deg; C-3200 &deg; C.

Storage Condition of Tantalum carbide TaC powder:

The coronavirus (COVID-19) pandemic not only had a significant impact on public health, it also severely affected one of the linchpins of the global economy – the tourism industry. As many countries introduced curfews and travel restrictions to contain the spread of the virus, travel across the world significantly declined from early 2020 onwards. The financial repercussions of the coronavirus have already begun to manifest themselves within the tourism industry. In 2020, global revenue from the travel and tourism industry was estimated to drop from a forecasted 711.94 billion U.S. dollars to 568.6 billion U.S. dollars, representing a decrease of over 20 percent. The region predicted to see the highest decline in revenue was Europe, decreasing from 211.97 billion U.S. dollars in 2019 to roughly 124 billion U.S. dollars in 2020.
The downturn in tourism has caused the recession, and the weakening of the economy has also affected the market demand for Tantalum Carbide powder. Recently, however, the demand for Tantalum Carbide powder has increased, so contact us for the latest news on Tantalum Carbide powder.
