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.

Tantalum Carbide’s main features
Tantalum carbide ceramic particles (TaC), which have a high melting point of 3880degC, high hardness (2100HV0.05), chemical stability, high electrical and thermal conductivity, and good chemical stability. Aluminum base and other substrates. Chao et al. The laser cladding technique was used to create a nickel-based reinforced tandemlum carbide surface composite material. Yu et.al. showed that the material’s hardness is significantly higher than pure nickel. The wear rate is also significantly lower than that in hardened steel. The relationship between in situ reaction directional solidification tantalum carbonide enhanced with base, chromium and aluminum bases and its microstructure. The results reveal that as solidification rate increases, so does the solid phase structure. Additionally, tantalum-carbidide volume fractions also change with solidification rate. Wang Wenli et al. The laser cladding technique was used to prepare an in-situ TaC alloy-enhanced nickel-based coating on A3-steel. Smooth surface with a strong metallurgical connection between the substrate and coating. Unfortunately, very few reports have been made about the in-situ generation of TaC from steel substrates. In this experiment, we used the surface ceramic particle reinforced iron matrix composite. TaC particles are used as the reinforcement phase. The micromorphology and reaction processes of TaC particles were studied in situ for reinforced iron-based surfaces composites.

What is Tantalum silicide?
Tantalum disilicide chemical formula is TaSi2. It has exceptional residential or commercial properties such as high melting factor, reduced resistivity, deterioration resistance, high temperature level oxidation resistance, and great compatibility with silicon, carbon as well as various other matrix products.

Tantalum disilicide Uses
Tantalum disilicide is mostly made use of in electric home heating elements, heat architectural elements, entrance materials, link circuits of incorporated circuits, heat oxidation resistance layers, cermets, ceramic matrix compounds, aerospace, engines, and various other areas.

Steel silicide
Tantalum disilicide is a kind of refractory steel silicide.
Steel silicide describes the tough compound created by change steel as well as silicon. Because of the huge span of silicon atoms, it can not create interstitial substances with change steels, so these hard substances have secure chemical structure and also great oxidation resistance.
Metal silicide has comparable electrical conductivity, heat performance, oxidation resistance and compatibility with silicon incorporated circuit manufacturing process. Transition steel silicide can be made use of for low resistance entrance and inner wiring, resistance contact.

Tantalum silicide Production
The preparation techniques of tantalum silicide consist of burning synthesis (CS) or self-propagating heat synthesis (SHS), as well as arc melting.

Burning synthesis or self-propagating high temperature synthesis is a method for the synthesis of intermetallic substances by the exothermic reaction of elements/ substances. It has the benefits of easy tools, reduced energy usage and brief synthesis time. Its main downsides are rapid reaction rate, tough process control and simple presence of various stages.
The burning synthesis of tantalum silicide requires pre-heating to start the response to realize the synthesis, but there is a stage besides disilicide.

Arc melting typically takes a long time to co-opt, and also the loss of silicon created by volatilization in the melting process might bring about the development of some pollutant phases. Due to its jet temperature approximately 10000 ℃ and also jet accelerate to 300-400m/ s, plasma spraying modern technology has the advantages of high temperature level melting, rapid solidification as well as near-net creating, and also it is not restricted by form or dimension, so it is very easy to understand its brief procedure developing, so it has gradually developed into a new kind of components developing innovation, which has actually been used to prepare some parts. Tantalum silicide powder is made into mass material by plasma splashing technology, which requires high pureness tantalum silicide powder as resources. Therefore, exactly how to obtain high purity tantalum silicide powder (without contamination phase formation) ends up being the key.
