Tantalum carbide powder 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 properties have 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 tantalum carbide melting point 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°C) and boiling point, at 5500 oC. 

The substoichiometric compound TaC0.89 has a higher melting point, near 4270 K (4000°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 ° 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 ° 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 ° C), Yang’s modulus (283-550 GPa), strong conductivity (32.7-117.4 μΩ · CM at 25 ° 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 ° C) and carbide (HFC) (melting point 3880 ° C), followed by carbide (ZrC) (melting point 3500 ° 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 ° C-3200 ° C.

Preparation Methods for Tantalum Carbide TaC powder
1. For TaC powder, mix tantalum pentoxide and solid carbon ball mills. At 1700, the mixture should be reduced and carburized in an oxygen-free atmosphere (mainly vacuum and argon atmospheres).
2. By heat treating in a non-oxidizing environment using the liquid precursor, nano tantalum caride powder was obtained. A small glass rod was used to stir 5mL of anhydrousethanol into a small vessel containing 0.50gTaCL5. The ultrasonic cleaner was heated to 55°C and operated at 40kHz. It produced 80W of power. After ultrasonic oscillation lasting 5-10min was completed, 0.10g nanoactivated carbon was added to the cleaner. The oscillation continued for 15-20 minutes. Then, pour it into the crucible. Coat it well on the inner wall. Dry it with a hot fan. The crucible containing the sample was placed into a vacuum hot pressing furnace at 1300 in a 100Pa vacuum or hydrogen atmosphere. At 1400 in an argon atmosphere, the holding time is 0.55h and the heating speed is 20/min. Use a brush to brush the products in crucible after the experiment.
3. Tantalum pentoxide can be converted to heat in the atmosphere Potassium pyrosulfate can be fused. Tantalum and carbon, or tantalum pentoxide, and black in an inert environment heated to 1900 reaction.

Tantalum disilicide Uses

What is Tantalum silicide?
Tantalum disilicide chemical formula is TaSi2. It has excellent properties such as high melting point, reduced resistivity, corrosion resistance, high temperature level oxidation resistance, and great compatibility with silicon, carbon and other matrix products.

Tantalum disilicide Uses
Tantalum disilicide is generally used in electrical burner, high temperature level architectural parts, gateway products, link circuits of incorporated circuits, high temperature oxidation resistance coverings, cermets, ceramic matrix compounds, aerospace, engines, and also other areas.

Steel silicide
Tantalum disilicide is a type of refractory steel silicide.
Steel silicide describes the hard compound formed by transition steel and silicon. Due to the big radius of silicon atoms, it can not develop interstitial compounds with shift steels, so these tough substances have secure chemical structure as well as good oxidation resistance.
Metal silicide has similar electric conductivity, heat performance, oxidation resistance and compatibility with silicon integrated circuit production procedure. Shift metal silicide can be used for low resistance entrance and also internal wiring, resistance call.

Tantalum silicide Production
The prep work approaches of tantalum silicide consist of combustion synthesis (CS) or self-propagating high temperature level synthesis (SHS), and also arc melting.

Combustion synthesis or self-propagating heat synthesis is an approach for the synthesis of intermetallic substances by the exothermic response of components/ compounds. It has the benefits of easy tools, low power consumption and also brief synthesis time. Its major drawbacks are quick response rate, difficult procedure control as well as simple existence of miscellaneous stages.
The burning synthesis of tantalum silicide needs pre-heating to initiate the response to understand the synthesis, however there is a stage apart from disilicide.

Arc melting typically takes a very long time to homogenize, as well as the loss of silicon brought on by volatilization in the melting process may result in the development of some contamination phases. Due to the fact that of its jet temperature level up to 10000 ℃ and jet quicken to 300-400m/ s, plasma splashing technology has the advantages of heat melting, rapid solidification and near-net forming, and it is not limited by shape or size, so it is easy to realize its brief process forming, so it has actually slowly created right into a brand-new sort of components developing modern technology, which has actually been used to prepare some components. Tantalum silicide powder is made into mass product by plasma splashing modern technology, which calls for high pureness tantalum silicide powder as basic material. As a result, exactly how to obtain high purity tantalum silicide powder (without impurity stage formation) ends up being the key.
