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 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.

About Niobium Carbide NbC Powder:
Niobium carbide (NbC) is an extremely hard refractory ceramic material used commercially for cutting tools. It is usually processed by sintering and is commonly used as a grain growth inhibitor additive in cemented carbides. Appearance is brown-gray metal powder, with purple luster. It is highly corrosion-resistant. Niobium carbide is one of the hardest technical compounds known. Niobium carbide, which has Young’s modulus of about 452 GPa, is a common product in micro-alloy steels because of its extremely low solubility in austenite, which is the lowest of all refractory metal carbides. This means that the micron-sized NbC precipitates are almost insoluble in the steel at all processing temperatures, and their location at grain boundaries helps prevent excessive grain growth in these steels. This is also a huge benefit for the base of micro-alloyed steel, as it is uniform and has a very fine grain size, ensuring toughness and strength. Tqhp is a trusted global Niobium Carbide NbC Powder supplier.

How is Tungsten Carbide WC Powder produced?
Using metal tungsten and carbon as raw materials, tungsten powder with an average particle size of 3 to 5 μm and carbon black of the same amount are dry mixed with a ball mill, fully mixed, press-molded, and placed into a graphite plate, and then placed in a graphite resistance furnace Or it can be heated to 1400～1700℃ in an induction furnace, preferably 1550～1650℃. In the hydrogen stream, W2C is initially produced and continues to react at high temperatures to produce WC. Or firstly, tungsten hexacarbonyl is thermally decomposed at 650-1000°C in the CO atmosphere to obtain tungsten powder, and then reacted with carbon monoxide at 1150°C to obtain WC. Temperatures higher than this temperature can generate W2C.
Chemical reaction formula:
2W + C = W2C
W + C = WC
Tungsten trioxide WO3 is hydrogenated and reduced to prepare tungsten powder (average particle size 3～5μm). Then, the mixture of tungsten powder and carbon black in an equimolar ratio (dry-blended with a ball mill for about 10 hours) is press-formed under a pressure of about 1t/cm2. Put the pressurized material block into a graphite pan or crucible, and heat it to 1400～1700℃ (preferably 1550～1650) in a hydrogen stream (using pure hydrogen with a dew point of -35℃) using a graphite resistance furnace or an induction electric furnace ℃), carburizing will produce WC. The reaction starts from around the tungsten particles, because W2C is generated at the beginning of the reaction, and because the reaction is incomplete (mainly because the reaction temperature is low), unreacted W and intermediate W2C remain in addition to WC. Therefore, it must be heated to the above-mentioned high temperature. The maximum temperature should be determined according to the particle size of raw tungsten. For coarse particles with an average particle size of about 150 μm, the reaction proceeds at a high temperature of 1550 to 1650°C.
Chemical reaction formula:
WO3 + 3H2 → W + 3H2O
2WO3 + 3C → 2W + 3CO2
2W + C = W2C
W + C = WC
