What is 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 significantly inhibits grain growth, with a density of 14.3g/cm3.

Tantalum carbide is insoluble in water, hardly soluble in inorganic acid, in a mixed acid of hydrofluoric acid and nitric acid, and can decompose. Strong oxidation resistance, easily melted and decomposed by potassium pyrosulfate. Tantalum carbide has 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, and shear stress.

As an important cermet material, tantalum carbide is sometimes added to the tungsten carbide alloy when commercially used for cutting applications.

Tantalum carbide melting point: Depending on the purity and measurement conditions, the melting point of tantalum carbide 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.
