What is tantalum carbide?

How strong is tantalum carbide?

By testing the Vickers hardness, fracture toughness and relative density of a series of samples, it can be confirmed that TaC has the best mechanical properties at 5.5 GPa and 1300°C. The relative density, fracture toughness and Vickers hardness of TaC are 97.7%, 7.4 MPa m1/2 and 21.0 GPa, respectively.

What is tantalum carbide?

Tantalum carbide is a light brown metallic cubic crystalline powder, belonging to the sodium chloride type cubic crystal system. Tantalum carbide is also used as a cemented carbide sintered crystal grain growth inhibitor, which has a significant effect on inhibiting crystal grain growth. The density is 14.3g/cm3, insoluble in water, hardly soluble in inorganic acid, soluble in a mixed acid of hydrofluoric acid and nitric acid, and can be decomposed. Tantalum carbide has strong oxidation resistance and is easily melted and decomposed by potassium pyrosulfate.

Surface gradient composites are tested from the surface to the substrate. Perform a microhardness test every 50μm from the surface. It can be seen from the measured hardness distribution that the surface microhardness value of the tantalum carbide surface gradient composite material is as high as 2123HV0.02. The microhardness of the nano-TaC layer is 1980-2025HV0.02, the microhardness of the micron-level TaC layer is 1750～2010HV0.02, and the microhardness of the TaC dispersion layer is 1640～1710HV0.02. As the distance from the surface increases, the microhardness of the TaC layer decreases, but its microhardness can still reach 5.5 to 7.0 times that of the gray cast iron matrix.

Overview of Tantalum Carbide

Tantalum carbide powder is insoluble in water, almost insoluble in inorganic acid, soluble in a mixed acid of hydrofluoric acid and nitric acid, and can be decomposed. Very strong anti-oxidation, easy to be melted and decomposed by potassium pyrosulfate. The room temperature resistance is 30Ω, showing superconductivity. (TaC) 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 parts to improve the toughness of the alloy. The main body of tantalum carbide (TaC) is golden yellow and can be used as an ornament of a watch.

Application of Tantalum Carbide

Tantalum Carbide (TaC) is an extremely hard (Mohs hardness 9-10) refractory ceramic material that is commercially used for cutting tool tips. Diamond exceeds the hardness.

It is a heavy brown powder, usually processed by sintering, and is an important cermet material. Sometimes used as a microcrystalline additive for tungsten carbide alloys.

The difference between tantalum carbide is that it is a stoichiometric binary compound with a known highest melting point of 4150 K (3880°C) and a boiling point of 5500 oC.

The substoichiometric compound TaC0.89 has a relatively high melting point, close to 427 (4000°C).
