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

Tantalum carbide TaC powder :
Tantalum carbide This is a metallic cubical powder, which is formed by a binary chemical family of tantalum with carbon. Ceramic materials with metallic conductivity that are extremely fragile and hard. They usually appear as powders of brownish-gray color and are processed by sintering. It belongs to the cubic sodium chloride system. It is used in cemented carbide sintered grains growth inhibitors, which have a density as high as 14.3g/cm3.

Tantalum carburide is insoluble, barely soluble, in organic acid. However, it can be decomposed in a mixture of hydrofluoric, and nitric acids. Strong resistance to oxidation, easily melted by potassium pyrosulfate and can be decomposed. Tantalum carburide has superconducting qualities and high electrical conductivity. Tantalum carbide can be used as a hard alloy tool, in tools and molds for wear resistance and corrosion, or to increase the strength of structural components. The golden yellow sintered body can be used for watch decorations.

These carbides are very hard due to their strong covalent components. TaC for example has a hardness of 1600-2100 kg/mm2 (9mH), whereas tantalum is 110kg/mm2 with 186gPa. TAC’s carbon content increases hardness and yield stress.

When tungsten-carbide alloys are used in commercial applications, tantalum carbide is added as an important cermet.
Tantalum carbide melting point This melting point is the highest among binary compounds. This value is highest among binary compounds. Only tantalum carbide ha has a slightly higher melt point, which is about 3942degC. Carbide clam’s melting point is similar to TaC.

Tantalum carbide Properties:
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 (3880degC) and boiling point, at 5500 oC.
The substoichiometric compound TaC0.89 has a higher melting point, near 4270 K (4000degC).

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.

Tantalum Carbide Uses :
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 mO * 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 damp reunion will affect TaC powder dispersion performance and using effects, therefore, Tantalum carbide TaC powder should be sealed in vacuum packing and stored in cool and dry room, the Tantalum carbide TaC powder can not be exposure to air. In addition, the Ti2AlC powder should be avoided under stress.
